Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuidevChapter 5: Using NC-Verilog with Synopsys Models2. Create a working directory and run flexm_setup to make copies of the model'sinterface and example files there, as shown in the following example:% $LMC_HOME/bin/flexm_setup -dir workdir model_fxYou must run flexm_setup every time you update your FlexModel installation witha new model version. Table 11 lists the files that flexm_setup copies to yourworking directory.Table 11: FlexModel NC-Verilog FilesFile Name Description Locationmodel_pkg.incVerilog task definitions for FlexModelinterface commands.

Update the clock frequency supplied in the model_user_pkg.inc file to correspondto the CLK period you want for the model. This file is located in:workdir/src/verilog/model_user_pkg.incwhere workdir is your working directory.4. Add the following line to your Verilog testbench to include FlexModel testbenchinterface commands in your design:`include "model_pkg.inc"NoteBe sure to add model_pkg.inc within the module from which you will beissuing FlexModel commands.Because the model_pkg.inc file includes references to flexmodel_pkg.inc andmodel_user_pkg.inc, you don’t need to add flexmodel_pkg.inc ormodel_user_pkg.inc to your testbench.October 6, 2003 Synopsys, Inc. 93
