Installation Overview
1.2 Installation Overview
Multicap 9 has three types of installation: Single User Edition, Network Edition, and
Multi-Station Standalone Edition.
Single User Edition – The Single User Edition is only licensed on the computer on which
you install it. If for any reason you wish to move the software to a different computer, you
must first uninstall it from the initial computer, and then re-install it onto the new computer. In
this case, you must contact Electronics Workbench to receive a new Release Code.
For details on the installation process see “1.3.2.1 Installing the Single User Edition” on
page 1-4”.
Maximum concurrent uses are limited to the number of seats you have purchased. A fixed
license allows only a set number of specific computers to run the software. You may select
and change the specific computers allowed access using the NLS Utility, up to the number of
fixed licenses you have purchased (see “1.4.2 Administering Fixed Seat Licenses” on
page 1-11).
Multi-Station Standalone Edition – If you are installing Multicap 9 on various computers in
a non-networked environment, then you are installing a Multi-Station Standalone Edition.
This type of installation is identical to that of the Single User Edition, except that you may
install a single copy of Multicap 9 per computer on as many computers as specified by the
License Agreement. For details on the installation process see “1.3.2.1 Installing the Single
User Edition” on page 1-4.
1.3 Installing Multicap 9
1.3.1 Before Installing Multicap 9
If you are upgrading to Multicap 9 from a previous version and wish to import your corporate
or user database, you will first need to make a back-up copy of the database.
ꢀ To back-up your database:
1. Browse to the directory location where you have your previous version of Multicap (for
example, C:\Program Files\Electronics Workbench\EWB8.
Multicap 9 User Guide

Installing Multicap
2. Copy the entire \database folder to a location that you will remember later (for example,
C:\Temp).
3. Your database is now safely backed-up.
Note You will require Administrator privileges to install Electronics Workbench software
and to enter release codes.
1.3.2 Single User Edition
You have been provided with a serial number that you will be required to enter at the time of
installation. The Single User Edition is only licensed on the computer on which you install it.
If for any reason you wish to move the software to a different computer, you must first
uninstall it from the initial computer, and then re-install it onto the new computer. In this case,
you must contact Electronics Workbench to receive a new Release Code.
1.3.2.1 Installing the Single User Edition
The Multicap 9 CD you received will autostart when inserted in the CD-ROM drive. Follow
the instructions below and on the screen during the installation process.
ꢀ To install Multicap 9:
1. Copy down the serial number you have received with your Multicap 9 package.
2. Exit all Windows applications prior to continuing with the installation.
3. Insert the Multicap 9 CD into your CD-ROM drive. When the splash screen appears, click
on Multicap 9 to begin the installation.
4. Follow the on-screen prompts to complete the installation.
1.3.2.2 Requesting a Release Code for the Single User
Version
Multicap 9 requires you to enter a Release Code within five days of the date of installation.
After the five day grace period has expired, Multicap 9 will not run until a Release Code is
entered.
To obtain your Release Code, you must provide us with the Serial Number and Signature, as
shown on the splash screen that displays when you launch Multicap. Contact Electronics
Workbench via our website (preferred method) at www.electronicsworkbench.com and select
the Product Registration link, or call Customer Service at 1.800.263.5552. Customers outside
North America should contact their local distributor.

Installing Multicap 9
Electronics Workbench recommends that you obtain your Release Code as soon as possible
after you have installed Multicap 9.
ꢀ To enter the Release Code:
1. Click on the Enter Release Code button at the start-up splash screen.
2. If you have received your Release Code via email there are a few ways to easily enter it
without the need to type each number or character one at a time. Select one of the
following methods:
• Highlight the Release Code. Drag and drop it on one of the text boxes.
• Highlight the Release Code, right-click on it and select Copy. Click on the Paste
Release Code button.
• Highlight the Release Code, right-click on it and select Copy. Right-click on one of
the text boxes and click on Paste from the pop-up menu.
3. If you have received your Release Code over the phone, you must type it in the Release
Code fields 5 characters at a time.
4. Click Accept to continue.
1.3.3 Multi-Station Standalone Edition
If you purchased the Multi-Station Standalone edition, you have been provided with one serial
number that you will use for each computer. You must then go to each computer on which
Multicap is installed, and separately request a Release Code for each, which enables the
software on that computer. Because of this inconvenience, and because of the fact that the
software is tied to particular computers, the Network Edition is the preferred alternative in
networked settings.
The Multi-Station Standalone Edition and Single User Edition installations are identical
except that you will re-use the same serial number multiple times.
1.3.4 Network Version
For network versions, the client software (Multicap 9) may be installed:
1. On a central file server that serves the software to other networked computers (called
"workstations").
2. Locally on each workstation computer. This option gives the best performance, as the
software need not be accessed across a network. However, it takes up the most disk space
on the workstation computers and requires updates to be installed separately on each
workstation. This option can be combined with option 1, where some workstations may

Installing Multicap
have the client software installed locally, and other workstations may have the software
served from a shared file system.
3. On several file servers, each one of which serves the software to a subset of the networked
computers, and, optionally, also on selected workstation computers. This option is
intermediate between options 1 and 2.
If options 1 or 3 are selected, the network must be set up to allow access from the
workstations to the shared file systems on which the client software is installed. For all of the
options above (1, 2 or 3), you must also install the Electronics Workbench Network License
Server (NLS) on any one computer on the network. This computer does not need to share a
file system with the client software. However, it requires TCP/IP access from the workstation
computers. This computer will run a Windows service that keeps track of and limits the
number of licenses currently in use. From that computer, administrators may run the NLS
utility that shows information on licenses available, the users currently utilizing the licenses,
and enables users to be remotely logged off.
As with the single user edition, you have been provided with a serial number that you will
require during each installation of Multicap 9 and for the lone installation of NLS. The serial
number identifies the product as being a Network Edition. Using NLS, you may access the
hardware signature of the NLS server computer. You must send the NLS server's hardware
signature and your serial number to Electronics Workbench. You will receive a Release Code
that you will need to enter into NLS to enable the network edition to function. The Release
Code encodes the number of seats and any term limits on your license.
A Multicap workstation will access either a fixed or a floating license depending upon the
serial number entered at the time of install of the Multicap 9 client software that the
workstation uses. In either the fixed or the floating case, the Multicap 9 client software may
be installed either directly on the workstation computer, or onto a shared file server. Different
serial numbers are provided to you for each of these cases.
Note NLS is only licensed on the computer on which you install it. If for any reason you
wish to move the NLS service to a different computer, you must first uninstall it from
the initial computer, and then re-install it onto the new computer. In this case, you must
contact Electronics Workbench to receive a new Release Code.
1.3.4.1 Installing the Network Edition
The Multicap 9 CD you received will autostart when inserted in the CD-ROM drive. Follow
the instructions below and on the screen during the installation process.
ꢀ To install Multicap 9:
1. Copy the serial number you have received with your Multicap 9 package.
2. Exit all Windows applications prior to continuing with the installation.

3. Insert the Multicap 9 CD into your CD-ROM drive. When the splashscreen appears, click
on Multicap 9 to begin the installation.
4. Follow the on-screen prompts to complete the installation.
Edition
After installing NLS, you will be required to enter a Release Code to enable the workstations
to run Multicap 9. (NLS is installed at the same time as the Multicap 9 Network Edition).
To perform this step, you will need to use the NLS Utility that you have previously installed
on your license server. See “1.4 Network License Server” on page 1-10 for further
information.
Note To obtain the Release Code, contact Electronics Workbench via our website (preferred
method) at www.electronicsworkbench.com and select the Product Registration link,
or call Customer Service at 1.800.263.5552. Customers outside North America should
contact their local distributor.
1.3.4.3 Workstation Setup
If for your Network Installation you choose to serve Multicap 9 from a file server to the
workstation computers, you will need to perform an extra setup step on each workstation
computer as follows.
1. Log on to each workstation with administrator privileges.
2. Using Windows Explorer, navigate to the <install-root>\EWB9\Setup folder on the
computer drive where Multicap 9 was installed on the network.
3. Double-click on setup.exe to install the shortcuts to the software on the computer. The
setup routine will configure the workstation.
Access to Multicap 9 directories should be restricted by placing certain user permissions on
various directories. Follow the instructions below to place the appropriate permissions.
1.3.4.4 Setting User Permissions
If you are installing the Multicap 9 Network Edition, you will need to set certain restrictions
on the folder where Multicap is installed in order to prevent non-administrative users from
modifying, writing or deleting program files that otherwise would make the software
unusable.
Note that there are many different ways to set permissions in a networked environment. The
following settings are one way of configuring a Windows XP Professional-based computer
that is not part of a network domain (i.e., using workgroup sharing). It is recommended that

detail.
1.4.4 Troubleshooting
The following contains solutions to situations that may be encountered with the
Network License Server.
•
Network License Server gives “Permission Denied” message.
For security reasons, the Network License Server may only be run from an account with
administrator privileges. Attempting to control the license server from a “user” or “power
user” account will cause a permission denied error.
•
Client application gives “Connection to the license server failed” message.
Make sure that the server address and port number on the client Network License Server
dialog have been set correctly. If you have entered a machine name as the server address,
try using the numeric IP address instead. In some networks, this IP address may change
dynamically. Please contact your network administrator for assistance if this occurs
frequently.

Client application gives “This product is not registered on the license server”
message.
Make sure that you have used the same product serial number on both the client and the
server.
Make sure that the registration code has been accepted by the license server. No client
application will be licensed until the product has been successfully registered.
Client application gives “No more instances of the program can be run on the
network” message.
This message is returned when all available license seats have been used up. When a user
shuts down the client application normally, their seat should be released immediately;
however, when a client application terminates unexpectedly (the computer is turned off
while running or there is a fatal error), the license server may take up to five minutes to
relinquish this license for reuse. If you believe that there should be seats available and
clients are being denied licenses, waiting for five minutes to log on is usually sufficient to
allow these seats to be freed.
The administrator may also wish to check the Network License Server control screen and
try to identify unused but unreleased licenses by their computer name or IP address
subdomain. If the administrator logs off these users, their licenses will be immediately
available for new clients. The administrator may also check for users running multiple
clients on a single machine.
In extreme cases, the administrator may click the Restart button on the Network License
Server. This will immediately release all licenses and then reissue them silently to active
authorized users only. For most client users, this will be an invisible process. This option
should however be used with caution: if the number of clients requesting licenses is
indeed over the seat limit, the license server cannot guarantee that exactly the same set of
clients will be granted licenses as had them before the reset operation. Therefore, some
authorized clients may be given the “no more instances of the program can be run on the
network” message in the middle of their active session and be prohibited from continuing
their work (however, they will be given the opportunity to save their work).

available, such as for RF simulation and extended parts libraries.
Ultiboard, fed from Multicap or Multisim, is used to design printed circuit boards, perform
certain basic mechanical CAD operations, and prepare them for manufacturing. Ultiroute is
an add-on to Ultiboard that provides automated parts placement and layout beyond what is
available in Ultiboard stand-alone.
All of the products in the Electronics Workbench suite are available in multiple tiers
depending upon budget and needs.
2.2 Multicap 9 Tutorial
This tutorial leads you through the schematic capture process. After following the steps
outlined on the following pages, you will have designed a circuit that will, when built, sample
a small analog signal, amplify it and then count the occurrences of the signal on a simple
digital counter.
Helpful tips are indicated by the presence of an icon in the left column, as in:
You can access the online help at any time by pressing F1 on your keyboard, or by clicking on

Wiring the Circuit
Multicap is modeless; there are no wiring or part placement modes to toggle between. All
components have pins that you use to wire them to other components or instruments. As soon
as your cursor is over a pin, Multicap knows you want to wire and the pointer changes to a
crosshair.

Introduction to Schematic Capture
4.1 Introduction to Schematic Capture
components you want to use, place them on the circuit window in the desired position and
orientation, wire them together, and otherwise prepare your design. Multicap lets you modify
component properties, orient your circuit on a grid, add text and a title block, add subcircuits
and buses, and control the color of the circuit window background, components and wires.
Note For details on setting up your workspace, refer to “3.4 Setting Schematic Capture
Preferences” on page 3-18.
4.2 Working with Multiple Circuit Windows
You can open as many circuits as you want at the same time. Each circuit appears in its own
circuit window. The active circuit window is, as in other Windows applications, the window
with the highlighted title bar. You can use the Window menu to move from circuit window to
circuit window or just click on the tab at the bottom of the workspace for the circuit you want
to see.
Each window is distinct, and can have its own preferences settings, set of components and so
on. You can copy, but not move, a component from one circuit window to another.
The first step in schematic capture is placing the appropriate components on your circuit
window.
You can use the following methods to locate a component in the database:
•
use the Component toolbar to browse through all the component groups, as explained in
“4.4.1 Using the place component browser” on page 4-4
•
search a specific component group/family of the database, as explained in “7.2.2
Searching for Components” on page 7-4.
Note There are multiple “levels” of the component database as discussed in “7.1.1 Database
Levels” on page 7-2.
The first of these choices is normally used. Each button on the Component toolbar
corresponds to a group of components with similar functionality. Clicking one of these
buttons opens the place component browser (i.e., the Select a Component dialog box) with the
contents of that button’s group displayed.

4.4 Placing Components
The component browser is used to select parts from the three databases and place them on a
circuit. It is designed to make it fast and easy to find the part you are looking for amongst the
more than 17,000 available.
Parts are organized by database, group, and family (for example, Master Database, Digital
Group, TTL Family). Filters are provided as appropriate to narrow lists based on value range
and tolerance where applicable. Type-ahead allows you to type a few characters to jump to the
component you are looking for. Search capabilities allow you to find parts using generalized
wildcard searches throughout all the databases.
By default, the Components toolbar is enabled. If it has been turned off, select
View/Toolbars/Components or right-click in the menu area and select Place Component from
the pop-up that appears.
Note This section describes the placement of “real” components. Use the Virtual toolbar to
place “virtual” components, as explained in “4.4.2 Placing Virtual Components” on
page 4-9.
ꢀ To choose and place a component.
1. Click on the desired group in the Component toolbar, for example, Basic. The Select a
Component dialog box appears with the selected component group displayed.
Alternatively, you can display the Select a Component dialog box by choosing
Place/Component and selecting the desired group from the Group drop-down list.

Placing Components
Note The Select a Component browser is also referred to as the place component browser.
Note The default database that displays in the browser is the Master Database. If you wish to
select a component from either the Corporate Database or User Database, you must
select that database from the Database drop-down list before selecting a component.
Once changed, the database will remain as selected for subsequent part placements.
2. Click on the desired component family in the Family list.
3. Click on the desired component in the Component list.
Tip To make your scroll through the Component list faster, simply type the first few
characters of the component’s name. As you type, matches are displayed in the top of the
Component list. If you make a mistake, you can use the BACKSPACE key to remove one
character at a time, or the DELETE key to remove all of the characters that you typed.

symbol and labels appear (unless you have specified that they are not to be displayed, as
explained in “5.1.1 Displaying Identifying Information about a Placed Component” on
page 5-2), as well as a unique RefDes made up of a letter and number. The letter
order in which the components were originally placed. For example, the first digital
component has the RefDes “U1”, the next is “U2”, the first inductor has the RefDes “L1”,
and so on.
Note If the component you place is a virtual component, it is a different color from real
components. This color is set in the Sheet Properties dialog box, as explained in
“3.4.2.1 Sheet Properties - Circuit Tab” on page 3-24.

4.4.1.1 Multisection Components
Certain non-virtual parts do not have a one-to-one correspondence with a footprint. Rather,
several circuit components may correspond to a single physical package. An example is a
quad 2-input NAND gate such as the Texas Instruments 7400N. For this example, up to four
components on a schematic diagram may correspond to a single part for the purposes of PCB
layout.
To place a multi-section part, you select the physical part from the component browser.
Immediately prior to placing the component, a section chooser pops up that lists parts that
have free sections, or allows you to start a new part. You must select one of these sections for
placement. Once placed, optimizing facilities are provided to enable multi-section parts to be
efficiently packed into chips, and a spare gate report is available to show sections not used on
multi-section parts in the circuit.
Refer to the following example for details.

4.5 Wiring Components
A basic wire can be created by clicking on any one of a part's symbol pins. This creates a wire
that can then be routed to either another symbol pin, or to another wire. If routed to a wire,
when placed a junction is automatically created to differentiate the case of two wires crossing
and two wires connected.
Wires can also be started by double-clicking anywhere on the circuit. This creates a junction
at that location and starts wiring from that point. If a symbol's pins are dropped onto either a
wire or another pin, a connection is automatically made.
Each time a wire is placed it either creates a new net, or joins an existing one. A net is a
collection of wires all of which define a common electrical potential. The term net is typically
used to describe this concept when discussing PCB layout. This concept is equivalent to the
concept of a node when discussing SPICE-based circuit simulation.
Nets are typically assigned the next available small integer value. If two nets are merged by
wiring them together, there are rules used to decide which of the two names the new net will
name to a net.
Within a single-page of a circuit, a net may be manually renamed to be the same name as
another on the same page. In this case, the two nets are merged together. This is called virtual
wiring and may be used to reduce the complexity of circuits. Except for special reserved nets,
virtual wiring may not be used across pages or across levels in the hierarchy. For details, see
“4.5.10 Virtual Wiring” on page 4-28.
Certain pre-defined named nets are considered global across an entire design. That is to say,
anytime a net at any level in the hierarchy or on any page is re-named to one of these reserved
nets, it joins this net. These reserved nets are 0, GND, VCC, VDD, VEE, and VSS. Net 0

Wiring Components
corresponds to analog ground. GND is a digital ground (as it is common for the purposes of
PCB layout to wish to isolate these two ground nets).
These reserved nets are most often used in conjunction with hidden symbol pins. These are
pins that are not shown on a schematic, as they and their accompanying wires would clutter
the schematic to too great an extent, but are nonetheless connected for the purposes of
simulation and layout. For example, a TTL digital AND gate would implicitly be connected to
GND and VCC via hidden pins.
4.5.1 Wiring Components Automatically
ꢀ To wire two components together automatically:

Note When wiring a component with multiple sections, an “X” indicates that a common pin
has been connected in another section of the component. In the example below, U5A
and U5B are sections of a Dual, Current Controlled Operational Transconductance
Amplifier. These two sections share a common pin on the IC (pin 11, VB+).
Pin 11 is connected
to Q1 from

Delete from the pop-up menu that appears.
4.5.3 Combining Automatic and Manual Wiring
You can combine the two methods of wiring when placing a single wire. When in autowiring
mode, Multicap assumes you always want to perform automatic wiring until you click
somewhere, which “locks” the wire to that point (this is manual wiring). Multicap then
continues with automatic wiring, until you click once more—either at a destination pin or
wire to complete the connection, or at another interim point on the wire you are placing. This
method allows you to use automatic wiring for most connections, and use manual wiring only
for difficult, critical or sensitive paths.
4.5.4 Marking Pins for No Connection
You can place NC (no connection) markers on selected component pins to prevent
inadvertantly wiring to these pins.

• Autowire when pins are touching — makes an automatic connection if a component pin
is touching a wire, another pin or a junction.
• Autowire on connection — chooses the most efficient path to wire the selected
components together. Disabling this option gives you more control over the wire path,
as Multicap follows the exact path of your cursor.
• Autowire on move — when you move a wired component, Multicap reshapes the wire
to the most efficient path. Disabling this option means that the wires will move exactly
in the shape and direction that you move a wired component.
• Delete associated wires when deleting — wires attached to a component will be deleted
when that component is deleted.

prototyped.
“Real” component with
footprint RES0.5
Same “virtual” component
- set to different values
However, when a “real” component is referred to in this guide, it corresponds to a real,
purchasable component with values that include footprints and package type for use in PCB
layout programs, like Ultiboard.
“Virtual” components, however, give you a means to experiment with a specific component’s
parameters early in the design process. Once you have determined the desired parameters, you
can replace the “virtual” component with a “real” component. Real components must be
replaced in order to provide alternate values (e.g., to substitute a 1kOhm resistor for a
3MOhm resistor).
For real components, the tab looks like this:

Virtual components are not real; that is, you could not go to a supplier and purchase them.
They have a symbol,but no footprint. They are provided for your convenience to allow you to
explore “what-if” scenarios. Multicap treats them slightly differently from real components.
By default, virtual components are shown in a different color from that of real components on
your schematic. This is to remind you that, since they are not real, these components will not
be exported to PCB layout software.
Virtual parts include all sources, virtual resistor/capacitor/inductor parts, and numerous
others.

6.1 Flat Multi-sheet Design
In many instances circuit designs are too large to fit all components on a single sheet or for
logical reasons it’s easier to think of a circuit design if it is divided. In this case, you can use
Multicap’s Flat Multi-sheet Design feature. This allows you to place off-page connectors
between different sections of your circuit.
ꢀ To add another sheet to a circuit:
1. Select Place/Multi-Page. The Page Name dialog box displays.
2. Enter the desired name and click OK. A blank circuit appears with the name that you
entered above.
3. Place components and wire the circuit as desired.
4. Select Place/Connectors/Off Page Connector. A “ghost” image of an off-page connector
displays attached to your mouse pointer.
5. Drag the “ghost” image to the desired location and click to place the connector. Repeat for
any other required off-page connectors.
6. Wire the off-page connectors into the circuit.
7. Save the file and return to the main circuit window.
8. Select Place/Connectors/Off Page Connector. A “ghost” image of an off-page connector
displays attached to your mouse pointer.

ꢀ To delete a page from a multi-page circuit file.
1. Select Edit/Delete Multi-Page.
2. Highlight the page that you wish to delete and click OK.
6.2 Hierarchical Design
Hierarchical blocks and subcircuits are used to organize functionally related parts of a design
into manageable pieces. Multicap’s hierarchical functionality allows you to build a hierarchy
of inter-connected circuits, increasing the reusability of your circuit designs and ensuring
consistency across a group of designers. For example, you might build a library of commonly
used circuits, stored in a central location. Those circuits could in turn be contained in other,
more complex circuits, which could be used to create yet another level of circuit design. Since
the interconnected circuits are linked together, and updated automatically, you can ensure that
refinements made to one circuit are carried out in all related circuits as well. This lets you, for
example, divide a complex project into smaller, interconnected circuits for completion by
individual team members.
Hierarchical blocks and subcircuits are similar except that subcircuits are saved with the
original circuit and hierarchical blocks are individual circuit files that are referenced from a
main file. The connection method is the same for both using the HB/SC Connector.
Sub-circuits are easier to manage, as they cannot accidentally become separated from the
circuit that references them. Hierarchical blocks are useful when re-using nested circuits
across multiple designs, or for dividing the work when multiple designers are working on the
same design.
When using hierarchical blocks, the “block” remains a separate schematic file which can be
edited. The connection between a block and the circuit in which it is placed is an active link
— if you place the contents of circuit A as a block of circuit B, you can open circuit A
separately, make any changes necessary, and those changes are reflected in circuit B the next
time you open it and in any other circuits that use circuit A.

Working with Larger Designs
6.2.1 Nested Circuits
When a circuit file is opened or created in Multicap, by definition it is the top-level circuit of
the current design. All circuits may reference other, embedded (subcircuit) or linked-to
(hierarchical block) nested circuits, which act as building blocks to control circuit complexity.
In addition, any circuit (nested or otherwise), may comprise multiple pages for ease of
understanding and printing. The Hierarchy tab in the Design Toolbox displays a graphical view
of the open designs.
If the same nested circuit is used more than once in a design, it will appear more than once in
the hierarchy view, and will have more than one tab in the main workspace. Each appearance
is an instance of use of that nested circuit. Use instances are identified by a path formed by the
names of the references used to reach them. In the simple example above, there are two ways
to reach "sub": one via the reference X1 in Circuit1 and one via the reference X2.
With one notable exception (RefDes assignment), edits made to one instance of use are
reflected in all others (because it is actually the same circuit that is being modified).
6.2.2 Component Numbering in Nested Circuits
Every part in a design has a unique reference designator (RefDes), such as R5, U2, and so on.
A RefDes is assigned by default when a component is placed by taking a single letter typical
of the type of part being placed (R for resistors, C for capacitors, and so on) followed by the
next highest available number. You may edit these to be anything you like, so long as they are
unique across a design. In the case of multi-section parts, the RefDes will also include the
section identifier.
6-4
Electronics Workbench
Download from Www.Somanuals.com. All Manuals Search And Download.
Hierarchical Design
The assignment of RefDes to part is stored with the top-level circuit, and not with any of the
nested circuits. This is because the same nested circuit may appear more than once in a
design. Were the RefDes to be associated with a nested circuit, duplicate RefDes would
appear in this situation. To combat this, it is the top-level circuit that associates a RefDes with
each part's instance of use. Thus, a hierarchical block opened via top-level circuit 1 will have
all the same components as are in the same hierarchical block opened via top-level circuit 2,
however they will have different RefDes.
In the above example, we see Circuit1 referencing the same sub-circuit, sub, twice. The
components, their placement, the wiring, and the net names in the sub-circuit are identical in
the two instances (because they are, after all, the same sub-circuit: sub). However, the RefDes
of their components are different, as the association of RefDes to component instance is
stored with and managed by the containing design, Circuit1.
6.2.3 Net Numbering in Nested Circuits
Net names are unique across all the pages of a multi-page circuit. However, net names may be
repeated in nested circuits. This does not cause any ambiguity, however, as the "real" names
of nets in nested circuits are formed by pre-pending a dot-separated path of references to

Working with Larger Designs
reach the circuit instance. In the diagram below, 'X1.IO1' is the full name of net number IO1
in the sub-circuit referenced by the RefDes 'X1' from the top-level circuit.
6.2.4 Global Nets
Certain pre-defined named nets are considered global across an entire design. That is to say,
anytime a net at any level in the hierarchy or on any page is re-named to one of these reserved
nets, it joins this net. These reserved nets are 0, GND, VCC, VDD, VEE, and VSS. Net 0
corresponds to analog ground. GND is a digital ground (as it is common for the purposes of
PCB layout to wish to isolate these two ground nets).
Components like VCC, VDD, etc. that use the "T" symbol; or the GND component that uses
the triangle symbol; can be renamed as desired. When a wire is attached to such a component,
the netname is automatically changed to the name of the component. For example, in the
diagram below, VCC was placed and then renamed to "power" by double-clicking on the
component and changing the RefDes to "power". The netname automatically changed to
"power" to match the new component RefDes.
All instances of VCC are
shown here.
Nets created this way become accessible across pages in a multi-page circuit, without the use
of Off-Page Connectors. If the symbol is placed into a nested circuit (SC or HB), the attached
6-6

Hierarchical Design
net is renamed to be a top-level net, and joins any other nets at the top-level with the same
name. For example, having a net named "power" in a sub-circuit referenced by X1 from the
top-level circuit would normally re-write the name of the net to "X1.power". This makes this
net unique to any other net named "power" at the top-level or in any other nested circuit in the
design (even other use instances of the same sub-circuit). However, placing a "T" component
re-named to be "power" and then attaching a wire to it would result in the net being simply
called "power". This creates a virtual wiring situation between all such nets named "power".
Hence, this is a mechanism by which nets may be declared to be of the top-most net
namespace, even when buried deeply into nested circuits.

6.4 Buses
In order to simplify wiring, buses may be used to carry multiple nets. Buses may be used
within a page, across pages, and down into nested circuits (subcircuits and hierarchical
blocks).
Buses operate in two modes. In net mode, a bus is simply a collection of nets. Each time a
wire is connected to a bus via a bus entry, you are given the choice of connecting that new
wire to an existing net already in the bus, or of adding that net to the bus.
In busline mode, you may pre-define the number and names of buslines that are contained in
that bus. When connecting a wire to the bus via a bus entry, you are prompted to specify
which of the existing buslines the new wire should attach to. All wires attached to the same
busline are merged into the same net.
Note The bus wiring mode is set in the Wiring tab of the Sheet Properties dialog box. See
“3.4.2.3 Sheet Properties - Wiring Tab” on page 3-27.

Buses
Net Mode
Busline Mode
Net mode is a more traditional way of using buses in schematic capture programs. Busline
mode allows for a more modern, declaration-before-use, approach to designing buses that
minimizes entry errors. Although you can switch between the two modes, you are encouraged
to use either one style or the other for any given circuit (switching from busline mode to net
mode loses information).
Buses exist in multiple bus segments. All bus segments with the same name are parts of the
same bus. They need not all be connected physically. To connect a bus to other pages of the
same circuit, a bus offpage connector is used. These work analogously to regular offpage
connectors in that they allow a bus to be continued onto a second or third page.
Bus Offpage Connectors
A nested circuit can use a Bus HB/SC Connector to specify that one of the pins of the
hierarchical block or subcircuit should be a bus pin. When using the nested circuit, attaching a
bus to such a bus pin brings up a dialog box asking you to map the buslines (or nets) of the bus
on the parent circuit to those in the nested circuit. This mapping is necessary as each instance

of a nested circuit may in general be connected to a different bus. If the bus in the parent
circuit is empty, no dialog will be presented and the bus will be wired in the natural manner.
Bus HB/SC Connector
To facilitate usage of buses, a powerful bus vector connect facility is provided that allows for
multiple pins of a chip to be connected to a bus in a single operation. This dialog allows you
to select pins from multi-pin components to connect to the buslines.

6.5 Variants
A variant is a specific version of a circuit. As PCBs are manufactured for distribution on a
global scale, some designs may require modifications depending on their target markets. For
example, power supply requirements for the European market differ from those of North
America. The variations in the power supply requirements may call for the use of different
components in a design. The designer would want to produce a single PCB which would meet
requirements for both the North American and the European versions. The board itself must
contain the traces as well as land patterns/footprints for both variations of the design. The
PCB would then be populated with components according to the target market of the device.

Project Management and Version Control
6.6 Project Management and Version Control
In order to help manage the various files associated with a design, Multicap Projects may be
used. A project is a collection of files. For example, all the circuit files making up a design
may be grouped together in a project, as well as external design documentation (written in
say, Microsoft Word), simulation output, reports, and PCB layouts generated with Ultiboard.
In fact, any file at all may be grouped into a project.
Facilities are provided to manage the files in a project as a whole: to version them, back them
up, restore them, move them, and lock files within them so that no two designers accidentally
work on the same file at the same time.
Note that even if a project contains a top-level circuit that references a hierarchical block, it is
not necessarily the case that the hierarchical block is in that same project. This is a choice left
entirely up to you. It may not be desirable to backup and version that hierarchical block with
the circuit that references it if, for example, the hierarchical block is accessed from many
different projects.

7.1 Structure of the Component Database
The Multicap component database is designed to hold the information necessary to describe
any component. It contains all the details needed for schematic capture (symbols) and PCB
layout (footprints), as well as other electrical information.
There are three levels of database provided by Multicap. The Master Database is read only,
and contains components supplied by Electronics Workbench. The User Database is private to
an individual user. It is used for components built by an individual that are not intended to be
shared. The Corporate Database is used to store custom components that are intended to be
shared across an organization. Various database management tools are supplied in order to
move components between databases, merge databases, and edit them.
All the databases are divided into groups and then into families within those groups.
When a designer chooses a component from the database and drops it onto the circuit, it is a
copy of the component that is placed onto the circuit. Any edits made to the component in the
circuit do not affect the original database copy, or any similar components previously placed
on the circuit. Likewise, any edits made the component in the database after a copy has been
dropped do not affect the previously placed components, but will affect all subsequently
placed ones.
When a circuit is saved, the component information is saved with it. On load, the user has the
option to keep the loaded parts as is, to make copies to place into their user or corporate
database, or to update similarly-named components with the latest values from the database.
7.1.1 Database Levels
Components are stored in three different database levels:
•
the Master Database stores the components as originally shipped with Multicap; these
remain the same and cannot be edited to ensure integrity of information.
Note Along with the footprint, manufacturer, symbol and other information that is available
through Multicap, this database also contains model information, which is only
available using Multisim, Electronics Workbench’s full schematic capture and
simulation software.
7-2
Electronics Workbench

Structure of the Component Database
•
•
the Corporate Database stores components selected and, possibly, modified or created by
an individual user or company/institution; these remain available to any other selected
users.
the User Database stores components modified, imported or created by you; these are
available only to you.
The User Database and the Corporate Database are empty when you first use Multicap. You
can use the User Database to store frequently used components or components you create
using Component editing (which is described in the following chapter).
The Corporate Database is primarily intended for companies/institutions (or individuals) who
work on projects where components with specific attributes are shared within a group or
project.
If you modify a component, thereby creating your own version, you must store it in either the
User Database or Corporate Database. You cannot modify the Master Database .
You can build a circuit that contains components from any or all of the available databases.
7.1.2 Classification of Components in the Database
Multicap divides components into logical groups. Each group contains families of related
components. The groups are listed below:
•
•
•
•
•

7.2 Locating Components in the Database
You can locate components in a specific component family within a specific database by
either browsing through the available data, which is the more common method, or by
searching for a component that meets specific criteria. These functions are described in this
section.
7.2.1 Browsing for Components
When you are placing a component, the browser dialog box that appears lets you browse for
components anywhere in the Multicap database. For details, see “4.4.1 Using the place
component browser” on page 4-4.
7.2.2 Searching for Components
Multicap comes with a powerful search engine to help you quickly locate components if you
know some information about the type of component you need. Multicap searches its database
for components that meet your criteria and presents them to you, enabling you to choose the
component that most suits the needs of your application from the list of candidates.
ꢀ To perform a standard search of the database:
1. Select Place/Component to display the Select a Component browser.
2. Click Search. The Search Component dialog box appears:
7-4
Electronics Workbench
Download from Www.Somanuals.com. All Manuals Search And Download.
Locating Components in the Database
3. Optionally, click More>> to display additional search options.
4. In the desired fields, enter your search criteria (you must enter at least one item). Enter
alphanumeric characters, that is, text and/or numbers. Case is not considered, and you can
use the “*” wildcard to search on partial strings.
For example, in the Footprint Type field:
• “CASE646-06” finds only the exact string “CASE646-06”
• “*06” finds any string ending with “06”
• “CASE*” finds any string starting with “CASE”
• a “?” anywhere in the string will match exactly one character. For example, “CAS?”
will match “CASE”, but not “CASE646-06”.
5. Click Search. When the search is complete, the Search Component Result dialog box
appears.
Tip The more specific your search criteria, the smaller the number of matching components.
ꢀ To select a component from the search results:
When the search is complete, the Search Component Result dialog box appears, displaying
information about the first component that matched your criteria. The Component list contains
Multicap 9 User Guide

Components
a list of all the components that matched your criteria. For example, using the search example
above, the results look like this:
Number of
components that
matched the
search criteria.
List of components
that matched the
search criteria.
Details of the
component
selected from
the list.
From the Component list, select the component you are interested in. To view information
about any component found by the search, simply choose it from the list and the display fields
change accordingly.
6. To place the selected component, click OK. You return to the Select a Component dialog
box, where you can place the component by clicking OK.
You can refine your search if your initial attempt yielded a large number of items.
ꢀ To refine your search:
1. Click Refine Search. The Refine Search dialog box appears.
Note The original search parameters remain in the Refine Search Component dialog until a
component is placed.
2. Enter desired parameters and click Search.
7.3 Types of Information Stored for
The Multicap databases store information about components in pre-defined fields (that is,
fields that are pre-filled in Multicap) and user fields (that is, fields you can use to capture
information that you want to record about a component).
Multicap also offers a detailed report of information about components and their packages.
See “9.2 Component Detail Report” on page 9-5 for details.

Component Editing
You can edit components in Multicap using the following methods:
•
•
Adding Components with the Component Wizard” on page 8-3
Component Properties dialog box — used to edit existing components and is accessed
from the Database Manager dialog box. For details, see “8.3 Editing Components” on
page 8-10.
You can modify any component stored in the Multicap component database. (See Chapter 7,
“Components” for more information on this database.) For example, an existing component
might now be available in a new package (originally pin-through hole, now surface mount).
You can easily copy the component information and change only the package details to create
this new component. You can also create your own component and place it into the database
or load a component from another source.
You cannot edit the Master Database. However, you can copy components to the corporate or
user database and then modify them as desired.
Tip Where possible, we recommend that you modify an existing, similar component, rather
than create one.
Each component in the component database is identified by the following types of
information, each of which are in a specific tab in the Component Properties dialog box. These
are described in subsequent sections of this chapter.
•
•
•
general information (such as name, manufacturer, date and author)
symbol (pictorial representation of the component for schematic capture)
footprint (the package that Multicap uses when exporting a schematic containing this
component to a PCB Layout package such as Ultiboard)
•
user fields (if used to further define the components)
In addition, components can be organized by using the Database Manager which lets you:
•
•
•
add and remove component families from the User or Corporate databases
modify user field titles for any database
add and change family icons.
Note If you modify any information about a component in the Master Database, you must
store the modified information in the User Database or Corporate Database database.
Caution If you modify information about any component in the
Corporate Database or User Database, you are prompted for a
new name for the component. If you do not give a new name,
Multicap saves the changes to the original location, so the
original User Database or Corporate Database component
information is overwritten.

Adding Components with the Component Wizard
Tip You can also edit components that you have already placed on the workspace. This can
be done using the component’s properties dialog box (double-click on the component to
display) and changing parameters in the various tabs. Changes made to placed
components in this manner will not be reflected in the database. If you place the same
component from the database, it will contain the parameters that it had before it was
edited. Edits to individual components can also be made via the Spreadsheet View.
8.2 Adding Components with the Component
Wizard
Multicap includes a Component Wizard to step you through the process of creating a
component.
ꢀ To create a component:
1. Click the Create Component button in the Main toolbar.

4. Click Select. You are returned to the Component Wizard. The Footprint Manufacturer and
Footprint Type fields have been populated based on the selected footprint.
Note You can also enter values directly into the Footprint Manufacturer and Footprint Type
fields instead of using the Select a Footprint dialog box. If you enter a value in either of
these fields that do not exist in the Master or User Database, you will be prompted to
confirm that you wish to add the information to a new footprint. If you select Yes, you
will be presented with the Add a Footprint dialog box. For details, see “8.7.2 Add a
Footprint dialog box” on page 8-44.
5. Specify the number of pins for the component (three, in this example). You have a choice
of selecting a single or multi-section component and the number of pins for each.

8.5.2.2 Working with the Symbol Editor
To use the Symbol Editor to create working symbols you need to be familiar with the elements
required to make up a symbol in Multicap. The key elements needed for a symbol are:
•
•
shape
pins
These are described in more detail in the following sections.
Shape
A symbol requires a shape to allow users to recognize its general function.
You use the drawing capabilities of Multicap’s Symbol Editor to construct a shape that makes
logical sense for the component you are creating or modifying. The simplest way to do this is
to edit the shape of an existing component. Once this is done, you must add pins.
Pins
There are three main parts to a pin. These are the:
•
Name — This is the name of the pin and is usually the same as that given in the data sheet.
For example, most digital parts have pins named “VCC” and “GND”. These names are
used to identify the actual name of the pin in the symbol and must be unique. It is
recommended that you use concise names as they display best on the workspace and on
printed output.
There are two methods to handle components that have more than one pin with the same
name:
1. Have one pin on the symbol that represents the duplicated pin (for example, “GND”)
and match the footprint pins later to the one on the symbol pin.
2. Add multiple pins that have the same basic name but append a digit to represent each
occurence. For example, you could represent multiple ground connections as GND1,
GND2, GND3, etc.
•
•
will match the numbering used in PCB layout. Within the Symbol Editor you only choose
whether to display the footprint pins by default, or not, and their orientation on the
workspace.
Shape — The shape of the pin denotes the type of pin. Multicap provides seven pin shapes
that you can use: Line Pin; Dot Pin; Clock Pin; Dot-Clock Pin; Input Wedge Pin; Output
Wedge Pin; Zero-Length Pin. For details, see “ Place Pin Toolbar” on page 8-34. The
shapes are used for identification purposes and do not have any impact on the operation of
the component.
Note The symbol and footprint pins must accurately map in order to transfer correctly to
PCB layout.

in the example shown below.
Note BGA pins in Ultiboard (Electronic Workbench’s PCB layout software), are named in a
matrix array starting with A1, A2…Ax; the next row would be B1, B2...Bx, etc. When
creating this symbol in Multisim, the footprint pins are initially named 1, 2, 3 etc… .
The functionality described in this step allows the footprint pins to be renamed to
match the alpha-numeric pin naming method used in Ultiboard. This feature is
especially useful for BGAs with large numbers of pins that would otherwise have to be
manually renamed.

Editing User Fields
8.8 Editing User Fields
User fields can be used for any purpose you wish. For example, you might use these fields to
record the cost of a component (the price you pay to the supplier or vendor), lead time for
ordering, preferred supplier, stock number, and so on. The information is particularly useful in
reports and in searching the database for the most appropriate component.
User fields consist of two elements: the field title and the field value. Field titles are shared
across databases (that is, all components in all the databases have the same user field titles),
and field values are unique to an individual component. Typically, a manager or project leader
in your company would populate this level of the database.
Note User fields must be given titles before they can be used to record values.
ꢀ To set up or modify user field titles:
1. Click the Database Manager button from the Standard toolbar.
Or
Choose Tools/Database/ Database Manager.
2. Click the User Field Titles tab.
3. Click the appropriate title until a frame appears around it.
4. Enter or change the name for the Title. This name will appear in the Component Properties
dialog box for all components in all databases.

10.1 Exporting to PCB layout
Multicap provides features that integrate with many PCB layout programs, and it is
particularly well-integrated with its sister product, Ultiboard.
In Multicap you define PCB Layers, and then constrain nets to be routed on these layers. You
can also indicate for specific nets the desired, min and max trace widths, min and max trace
lengths, minimum distances to other traces, pads, vias, and so on. As well, Multicap will keep
Multicap 9 User Guide

Transfer/Communication
track of power and ground nets, and constrain them to be routed only on layers of the
appropriate type.
When the schematic has been prepared, the design will be flattened and consolidated, and
transferred to Ultiboard for board layout. In Ultiboard you design the board shape and size,
place the components on the board, and route the nets as copper traces on as many layers as
you like, placing vias to connect traces between layers. Ultiroute, and add-in product to
Ultiboard, is used to both place parts and to route traces automatically. Periodic animations of
the layout in intermediate autorouting stages help you to gauge Ultiroute progress.
The Multicap/Ultiboard libraries also contain full 3D mechanical CAD information for boards
and parts. A 3D view of the board enables you to quickly preview the mechanical properties
of the board. A small mechanical CAD package in Ultiboard allows for quick casing designs.
For larger jobs, the 3D board information can be exported to popular mechanical CAD
packages.
In order to enable better routing, Ultiboard and/or Ultiroute may wish to swap pins of
components (e.g., swap the two inputs of an AND gate), or may wish to swap sections within
a component (e.g., use a different gate in a QUAD AND chip). Multicap provides Ultiboard
with all the information required to do this.
Changes made in Ultiboard (either automatic ones or manual ones) can be "back annotated" to
Multicap. For example, if a component is renamed, swapped with one another, pins are
swapped, parts are deleted, and so on. The changes will be made into the schematic in
Multicap as well. Likewise, subsequent changes to the schematic in Multicap can be "forward
annotated" to Ultiboard, in order that progress to date on a board design is not lost if a small
change in the schematic is made. Both programs have a feature called "cross probing", which
enables parts or nets in one application to be quickly found in the other.
Taken together, Multicap (with MultiVHDL), and Ultiboard (with Ultiroute) provide a
complete end-to-end solution for circuit and PCB design.
