Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 1: Using Synopsys Models with Simulatorsf. For Linux:% mkdir workdir% flexm_setup -dir workdir model_fx% gcc -o executable_name \your_C_file.c \workdir/src/C/x86_linux/model_pkg.o \${LMC_HOME}/lib/x86_linux.lib/flexmodel_pkg.o \-Iworkdir/src/C \-I${LMC_HOME}/sim/C/srcThe C executable file that you created in this step is the program that you point to usingthe FlexCFile SWIFT attribute for the model instance in your design.Using DesignWare Memory Models withSWIFT SimulatorsDesignWare Memory Models (DWMM) are binary simulation models. All DWMMmodels have an _mx extension in the model name: model_mx.DWMM models are available on several SWIFT simulators. This manual explains howto connect these models to the supported simulators.Regardless of the simulator you use, you must configure your DWMM models for thesimulator using the required SWIFT parameters, as explained in the next section.DesignWare Memory Model SWIFT ParametersDWMM model attributes — or parameters — are model-specific values needed by thesimulator to configure a model. You configure DWMM models when you instantiatethem in your design using these SWIFT parameters. This could take the form of Verilogdefparams or VHDL generics, or symbol properties depending on the simulator you areusing. Table 5 explains how to configure DesignWare Memory Models using therequired SWIFT parameters.Table 5: DesignWare Memory Model SWIFT ParametersParameter Usage Valid Values, Examples, &DefaultsModelIdUse this parameter to specify a uniquehandle for a model instance. You use theModelId in testbench commands to modelinstances. The ModelId is also used inmessages to indicate which model instanceis issuing the message.Valid values are positive integers inquoted strings, and “-2”.Example: “8”Default: “-2”Note: Do not use the “-2” defaultvalue.October 6, 2003 Synopsys, Inc. 29
