Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys ModelsSimulating with Hardware Models in QuickSim IIOnce you have registered each hardware model in your design and set the MODELproperty to the appropriate label for instances that reference those models, you are readyto simulate. You can use the SIGnal INSTance command to turn on and off a number ofQuickSim II or hardware modeling features for selected instances during simulation.Signal Instance Command SummaryTable 27 provides a summary of these features and the specific commands used toimplement them; the subsections that follow describe the features in more depth. Somefeatures can also be implemented through Shell Software statements or the lm utilities;for details, refer to the Shell Software Reference Manual. For instructions on how toselect one or more instances, refer to your QuickSim II documentation.NoteIf the simulator is reset with the $reset_state function, any prior SignalInstance commands are lost because the simulator is reset to the same state itwas at invocation.Table 27: Signal Instance Command SummaryFeature Command DescriptionModel evaluation enable Enables evaluation of the instance byQuickSim II (default)Timing shellselectiondisablelst [-p all]nolst [-p all]Disables evaluation of the instance byQuickSim IISelects hardware model Shell Software files todescribe the instance’s timingSelects the Technology File to describe theinstance’s timing (Default)October 6, 2003 Synopsys, Inc. 177
