Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 8: Using Scirocco with Synopsys ModelsUsing SmartModels with SciroccoTo use SmartModels 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. To create SmartModel VHDL templates, check to see if you have write permissionfor $LMC_HOME/synopsys/smartmodel; if so skip to Step 5. Otherwise, open thesynopsys_sim.setup file in your current working directory and search for the stringSMARTMODEL. By default, the logical library name SMARTMODEL is mappedto $LMC_HOME/synopsys/smartmodel, as follows:SMARTMODEL : $LMC_HOME/synopsys/smartmodel3. Change the directory to one where you have write permissions, as shown in thefollowing example:SMARTMODEL : ~/smartmodel4. Generate a VHDL model wrapper file for the model by invokingcreate_smartmodel_lib with any optional arguments. For complete information onthe syntax for this command, refer to “create_smartmodel_lib CommandReference” on page 194.% $SYNOPSYS_SIM/sim/bin/create_smartmodel_lib arguments5. If you changed the SMARTMODEL mapping in Step 3, you must use the -srcdiroption to specify that directory. Also, you can save time by using the -model or-modelfile option to specify the models you want. Otherwise, the script processes allinstalled SmartModels. For example, here is a recommended set of options to usefor one SmartModel (ttl00 in this example):% $SYNOPSYS_SIM/sim/bin/create_smartmodel_lib -model ttl00 \-srcdir ~/smartmodel6. After create_smartmodel_lib finishes executing, verify that the VHDL templatefiles were created in the appropriate directory.7. To use SmartModels in the VHDL source file of your design, specify theSMARTMODEL library and instantiate each SmartModel component. In the VHDLdesign file that uses SmartModel components, enter the following library and useclauses:library SMARTMODEL;use SMARTMODEL.components.allThe library logical name SMARTMODEL must be mapped to appropriatedirectories in your synopsys_sim.setup file.October 6, 2003 Synopsys, Inc. 193
