Chapter 7: Using QuickSim II with Synopsys ModelsSimulator Configuration GuideUnsupported QuickSim II CommandsTable 23 lists several common QuickSim II simulation commands that are not supportedby DWMM models, and the effects these commands have if used with DWMM models.Table 23: Common Unsupported QuickSim II CommandsQuickSim II CommandREREAD MODELFILERESTORE STATESAVE STATEWRITE MODELFILEEffect on DWMMDoes not cause a DWMM model to reload itsmemory image file. If this command is issuedanytime after time 0, the DWMM model may notsimulate correctly.Attempting to restore the saved state of a DWMMmodel crashes the model, and subsequently thesimulation.Not harmful, but the resulting saved state cannot beused to restore the simulation state since RESTORESTATE is fatal.Not harmful, but does not cause a DWMM model tosave a memory image file.SWIFT Command ChannelDWMM models are not designed to use the SWIFT command channel. Nevertheless,the models support the following two commands, both of which are issued using theQuickSim II command SIGNAL INSTANCE.●●ReportStatus — prints a message that describes the configuration status of a model.To issue ReportStatus for selected instances:$signal_instances("swift_model", "ReportStatus", "model_name");Trace ON | OFF — when enabled (“ON”), traces the SWIFT simulation session, andcreates an “lmc_trace.out” file.To enable tracing for selected instances:$signal_instances("swift_session", "Trace on", "model_name");For more information on using the SWIFT command channel, see “The SWIFTCommand Channel” on page 21.160 Synopsys, Inc.

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys ModelsChecking the Model’s StatusTo check the status of a DWMM model, use the QuickSim II SIGNAL INSTANCEcommand to query the model directly. For example:$signal_instances("swift_model", "ReportStatus", "/$I1");’/I$1’: ’ ’’/I$1’: ’Note: ’’/I$1’: ’ Model Logical Name: ssram08x1k_mx’’/I$1’: ’ Model Physical Name: ssram08x1k_mx’’/I$1’: ’ Model ’.mdl’ Version: 01004’’/I$1’: ’ Model Directory: /d/tools/lmc_home/models/ssram08x1k_mx’’/I$1’: ’ Model ’.lmc’ Name: /d/tools/lmc_home/data/solaris.lmc’’/I$1’: ’ Model-reported Version of Main Shared Library: 01001’’/I$1’: ’ Model-reported Version of SmartLink Interface: v1.0’’/I$1’: ’ InstanceName: /I$1’’/I$1’: ’ DefaultData: 00000000’’/I$1’: ’ DelayRange: TYP’’/I$1’: ’ MemoryFile: U1_memory_image’’/I$1’: ’ MessageLevel: 15’’/I$1’: ’ ModelAlias: .’’/I$1’: ’ ModelConfig: 32’h0’’/I$1’: ’ ModelId: -2’’/I$1’: ’ TimingVersion: 10’’/I$1’: ’ ModelMapVersion: 01002’’/I$1’: ’ Timing Constraints: Off’’/I$1’: ’ Max Simulation Time Unit: 10**(-10) seconds’’/I$1’: ’ SmartModel Instance /I$1(U1:10), sheet1 ofschematic at time 3600.00 nsec’You can also use the QuickSim menu to request a report on selected or specified objects.For example, the following command would issue a status report for each selectedinstance in the design:QuickSim > Report > Object > SelectedReconfiguring Models for SimulationYou can use QuickSim II to reconfigure models for additional simulations by doing thefollowing:●●●Editing propertiesChanging timing modes of model instancesEnabling or disabling constraint checkingOctober 6, 2003 Synopsys, Inc. 161
