Chapter 7: Using QuickSim II with Synopsys ModelsSimulator Configuration GuideQuickSim II Command Line SwitchesWhen QuickSim II is invoked from the command line, the following switches are theonly ones recognized by SmartModels.Timing Mode SwitchUse the -timing_mode switch to set the global timing mode to minimum, maximum, ortypical. Unit delay timing mode is not currently supported. Use the following syntaxwhen setting this switch:-timing_mode { min | max | typ }Time Scale SwitchUse the -time_scale switch to adjust time values (delays and checks) to the desiredresolution by specifying the time scale in nanoseconds (ns). The default is 0.1 ns. Usethe following syntax when setting this switch:-time_scale timescaleConstraint Mode SwitchUse the -constraint_mode switch to enable or disable timing constraint checking. Thedefault is “off”. Any value other than “off” causes a model to perform constraintchecking. Use the following syntax when setting this switch:-constraint_mode { off | state_only | messages }136 Synopsys, Inc. October 6, 2003
Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys ModelsQuickSim II Command InteractionThere are many QuickSim II simulator commands that interact with SmartModels in adesign. Table 17 lists some of the QuickSim II commands that affect SmartModels.Table 17: QuickSim II Command InteractionQuickSim II CommandINITIALIZESIGNAL INSTANCEREPORT OBJECTREREAD MODELFILERESET STATERESTORE STATESAVE STATEWRITE MODELFILEEffect on SmartModelsCauses a model to reevaluate until the simulationreaches DC stability. It will not reset the model orset internal values to the “state_value” specified.Reports the status of selected instances with the“swift_dump” parameter.Not supported by SmartModels. Use the SIGNALINSTANCE command to query a model and reportits status.Reloads any of the configuration files used by amodel, including memory image, JEDEC, MCF,SCF, and PCL command files. Configuration filesare only re-read if the simulation has changed theconfiguration.Causes all models to reinitialize their states to theoriginal time zero (power-up) conditions.Restores all of the model's internal states as part ofthe operation.Records all of the model's internal states as part ofthe operation.Causes a model to “dump” its memory image to afile.SWIFT Command ChannelYou can use the SWIFT command channel to pass commands directly through toSmartModels. Use the QuickSim II SIGNAL INSTANCE command to access thecommand channel.To issue a command for selected instances, use the following:signal instance swift_model -p “command_name [ arguments ]”October 6, 2003 Synopsys, Inc. 137
