Simulator Configuration Guide for Synopsys Models

Chapter 7: Using QuickSim II with Synopsys ModelsSimulator Configuration GuideIf the TimingVersion property value is not specified, the default timing version isactivated. If a symbol is not specified when applicable, the default is used. The defaultsare “positive” for logic version, and “pin” for symbol type.Selecting Alternate SymbolsWhen there are DeMorgan equivalent symbols, the positive version is the default.Specify “NEG” as the symbol name to get the negative logic symbol (if desired), asfollows:% $add_instance (“$LMC_HOME/special/qsim/symbols/ttl00”,”NEG”,,, \[“TimingVersion”,”SN74AS00”])When activating parts manually, remember that the pin symbol is the default when bothpin and bus symbols are available. Specify the bus symbol (if desired), as follows:% $add_instance (“$LMC_HOME/special/qsim/symbols/mc68030_hv”,”BUS”,,, \[“TimingVersion”,”MC68030-33”])Use the Mentor Graphics Design Viewpoint Editor (DVE) to set the primitive type forSWIFT in DVE. To ensure that SWIFT instances are evaluated as primitives, you canadd to the primitive rule using the add primitive command within DVE. In the followingexample, the add primitive command causes all instances of the MODEL property value“SWIFT” to be evaluated as primitives by QuickSim II.% add primitive “model” -noexcept -string “SWIFT”The string “SWIFT” can be substituted with any other labels that you have registeredwith the model type of “swift”.Logic SimulationThe following sections in this chapter provide information about using SmartModels forlogic simulation in the Mentor Graphics’s QuickSim II environment.
