Step 7B: Set up ModelSim to use SmartModels

Although ModelSim PE/SE supports the SWIFT interface, certain modifications must be made to the

default ModelSim setup to enable this feature. The ModelSim installation directory contains an

initialization file called modelsim.ini. In this initialization file, you may edit GUI and simulator settings

so that they default to your preferences. You must edit parts of this modelsim.ini file in order for it to

work properly with the Virtex-II Pro device simulation models.

The following changes should be made to the modelsim.ini file located in the ModelSim installation

directory. (An alternative to making these edits to the installation directory is to change the MODELSIM

environment variable so that it points to an edited modelsim.ini file located in another directory.)

Edit modelsim.ini

1.  Edit the statement "Resolution = ns" and change it to "Resolution = ps".

2.  Comment the following statement called "PathSeparator = /" by adding a ";" at the beginning of

the line.

3.  For Verilog designs enable SmartModels by searching for the variable "Veriuser" and change it

to:

On Windows:

Veriuser = $MODEL_TECH/libswiftpli.dll

On Solaris:

Veriuser = $MODEL_TECH/libswiftpli.sl

4.  Search for the [lmc] section and uncomment the “libsm” and “libswift” definitions according to

your operating system.  Comment out other “libsm” and “libswift” definitions.

For Example,

On Windows, uncomment these lines:

libsm = $MODEL_TECH/libsm.dll

libswift = $LMC_HOME/lib/pcnt.lib/libswift.dll

On Solaris, uncomment these lines:

libsm = $MODEL_TECH/libsm.sl

libswift = $LMC_HOME/lib/sun4Solaris.lib/libswift.so

Note: It is important to make the changes in the order in which the commands appear in the

modelsim.ini file. The simulation may not work if the order is changed.

After you finish editing the modelsim.ini file, make sure that your environment is set to run ModelSim.

Windows

Set Environment

Set the variables to the following values:

MODELSIM \modelsim.ini

PATH \win32;%PATH%

You are responsible for changing the parameters included within  to match the systems

configuration.

Note: %PATH% represents what your PATH variable had before doing the changes. Make sure you

keep that.
