Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 8: Using Scirocco with Synopsys ModelsUsing DesignWare Memory Models withSciroccoDesignWare Memory Models (DWMM) are SWIFT-compatible binary simulationmodels that have an _mx extension (for example, model_mx). To use DWMM modelswith Scirocco, follow these steps:1. Make sure Scirocco is set up properly and all required environment variables areset, as explained in “Setting Environment Variables” on page 191.2. Create slm_lib and work directories, as shown in the following examples:% mkdir ./slm_lib% mkdir ./work3. Create the logical to physical mapping for the slm_lib, work, and default libraries bymodifying your local synopsys_sim.setup file to include the following lines:WORK > DEFAULTDEFAULT : ./workSLM_LIB : ./slm_lib4. Set your simulation timebase by modifying your local synopsys_sim.setup file toinclude a TIMEBASE entry, as shown in the following example:TIMEBASE = PS5. Compile the required Synopsys libraries into the slm_lib library, as shown in thefollowing example:% vhdlan -w slm_lib $LMC_HOME/sim/vhpi/src/slm_hdlc.vhd% vhdlan -w slm_lib $LMC_HOME/sim/vhpi/src/mempro_pkg.vhdCautionDo not use the Scirocco -noevent switch when compiling the slm_hdlc.vhdpackage. This can cause the package to compile incorrectly.6. Add slm_lib LIBRARY and USE statements to your testbench:LIBRARY SLM_LIB;USE SLM_LIB.components.all;USE SLM_LIB.mempro_pkg.all;7. Create the model’s bused wrapper as shown in the following example:% $SYNOPSYS_SIM/platform/sim/bin/create_smartmodel_lib -create \-srcdir . -model model_mxThis step produces a components.vhd file and an entities.vhd file. The model_mxmodel is defined in the entities.vhd file.October 6, 2003 Synopsys, Inc. 199
