Simulator Configuration Guide for Synopsys Models

Chapter 8: Using Scirocco with Synopsys ModelsSimulator Configuration GuideUsing FlexModels with SciroccoTo use FlexModels with Scirocco, follow this procedure:1. Make sure Scirocco is set up properly and all required environment variables areset, as explained in “Setting Environment Variables” on page 191.2. If you want the improved performance that comes with bused wrappers, generate aVHDL model wrapper file by invoking create_smartmodel_lib with any optionalarguments. For more information on the syntax for this command, refer to“create_smartmodel_lib Command Reference” on page 194.% $SYNOPSYS_SIM/sim/bin/create_smartmodel_lib argumentsNoteThe bused wrappers enable improved performance but do not work with theexamples testbench shipped with the model. To exercise the examplestestbench, use the wrappers shipped with the model (see Table 28), asexplained in the rest of this procedure. If you are using the bused wrappers,adjust accordingly.3. 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 28 describes the FlexModel Scirocco interface andexample files that the flexm_setup tool copies.Table 28: FlexModel Scirocco VHDL FilesFile Name Description Locationmodel_pkg.vhdModel command procedure calls for HDLCommand Mode.workdir/src/vhdl/model_user_pkg.vhd Clock frequency setup and usercustomizations.workdir/src/vhdl/model_fx_vss.vhd A SWIFT wrapper for the model. workdir/examples/vhdl/model_fx_comp.vhdComponent definition for use with the modelentity defined in the SWIFT wrapper file.
