Compile the sim_user.c file to create the sim_user.o file.Creating a VERA TestbenchTo create a VERA testbench to use with FlexModels, follow these steps:1. Include the header files.Table 31 lists the two required header files.Table 31: VERA Header FilesFile Name Description Locationflexmodel_pkg.vrhmodel_pkg.vrhContains definitions for generic constantsuseful in FlexModel commands.Contains definitions for model class andmodel-specific constants useful inFlexModel commands.$LMC_HOME/sim/vera/src$LMC_HOME/models/model_fx/model_fxversion/src/vera2. Create an instance of the ModelFx (or ModelFz) class.Before using FlexModel commands, you must create an instance of the ModelFx orModelFz class in the VERA testbench.3. Send commands to a FlexModel through the model’s methods.In VERA Command Mode, you can use the same FlexModel features andcommands that you use in HDL Command Mode. There are a few differences incommand usage, however; refer to “Command Syntax Differences in VERACommand Model” in the FlexModel User’s Manual. For details on specificcommands, refer to “FlexModel Command Reference” in the FlexModel User’sManual.210 Synopsys, Inc. October 6, 2003
Simulator Configuration GuideChapter 9: Using VERA with Synopsys ModelsVERA Testbench ExampleThe following example shows how to incorporate FlexModels in a VERA testbench.#include #include “flexmodel_pkg.vrh”here#include “model_pkg.vrh”constants defined hereprogram model_test{// Vera Defines// FlexModel generic constants defined// Model class, and model-specific/** Create an instance of the model, argument 1 to the* constructor is the string name of the instance in* top level Verilog/VHDL testbench.* argument 2 is the path to the models clock pin* Here the assumption made is that the model is* instantiated in a Verilog testbench* Since the constructor has been called, this will* return at the next posedge of u1.CLK.*/ModelFx model_1 = new(“modelInstName_1”, “u1.CLK”);// Create another instance, since time has already elapsed// above, this call will return immediately.ModelFx model_2 = new(“modelInstName_2”, “u2.CLK”);// NOTE : This example assumes that the aguments to the// methods have been defined in the VERA testbench.// Check that no errors have occuredif ( model_1.showStatus() == FLEX_VERA_FATAL ||model_2.showStatus() == FLEX_VERA_FATAL ) {}// Errors exist, take suitable actionfork{// Send commands to the FlexModel Instance 1// Note that the id is encapsulated in the model// class and thus is not an argument to the commands.model_1.write(address1, data1, ‘FLEX_WAIT_F, status);model_1.write(address2, data2, ‘FLEX_WAIT_F, status);model_1.write(address3, data3, ‘FLEX_WAIT_F, status);October 6, 2003 Synopsys, Inc. 211
