Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 9: Using VERA with Synopsys ModelsIncorporating FlexModels in a VERA TestbenchTo incorporate FlexModels in your VERA testbench, use the following procedure. Formore information on creating VERA interface files and using models in VERA, refer tothe VERA User Guide.1. 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:% $LMC_HOME/bin/flexm_setup -dir workdir model_fxYou must run flexm_setup every time you update your FlexModel installation witha new model version. Table 32 lists the files that flexm_setup copies to yourworking directory.Table 32: FlexModel VERA FilesFile Name Description Locationmodel_pkg.vrmodel_pkg.vrhContains FlexModel VERA class andmethod definitions.Contains model definitions for use inVERA testbenches.workdir/src/veraworkdir/src/vera2. Set the VERA_HOME variable to point to the location of your VERAinstallation directory:% setenv VERA_HOME path_to_VERA_installation3. Compile the VERA source files in the LMC_HOME tree.You need to compile three files: lstmodel.vr, swiftmodel.vr, and flexmodel_pkg.vr.The following is a sample compile script:% vera -cmp -I$LMC_HOME/sim/vera/src/lstmodel.vr% vera -cmp -I$LMC_HOME/sim/vera/src/swiftmodel.vr% vera -cmp -I$LMC_HOME/sim/vera/src/flexmodel_pkg.vrIf you are using VERA version 4.0 or earlier, you must compile theflexmodel_pkg.vr object with a “VERA_4” preprocessor flag. Your compile linewould therefore look like the following example:% vera -cmp -I$LMC_HOME/sim/vera/src/flexmodel_pkg.vr -DVERA_44. Compile the model’s VERA source file, model_pkg.vrThis file includes the flexmodel_pkg.vrh file, but the VERA compiler needs to findthe other header files too; therefore, you must include the path to the other headerfiles. The following is a sample compile script:% vera -cmp -I$LMC_HOME/sim/vera/src -Iworkdir/src/vera \workdir/src/vera/model_pkg.vrOctober 6, 2003 Synopsys, Inc. 213
