Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys ModelsThe LMC_USE_32BIT environmental variable is a “set/no-set” variable. That is, youcan set it to any value (even zero) to turn on 32-bit support on a 64-bit platform. If youdo not set it at all, the default condition is 32-bit models on 32-bit platforms, or 64-bitmodels on 64-bit platforms. You only set this environmental variable (to any value)when you are on a 64-bit platform using 32-bit models and simulators.Using SmartModels and FlexModels withQuickSim IINoteQuickSim II cannot simulate 64-bit FlexModel or 64-bit SmartModels.This section explains how to use SmartModels and FlexModels with QuickSim II. Touse FlexModels with QuickSim II, you use C-only Command Mode. For information onC-only Command Mode, refer to “Using FlexModels with SWIFT Simulators” onpage 23. The rest of this section explains required installation steps and how to usemodel symbols in the schematic capture front-end to the simulator. This information isorganized in the following major subsections:● “Installing the QuickSim II SWIFT Interface” on page 125● “Using SmartModels/FlexModels with QuickSim II” on page 127● “Schematic Capture” on page 127● “Logic Simulation” on page 134● “Custom Symbols” on page 144Installing the QuickSim II SWIFT InterfaceSynopsys ships the part of QuickSim II that communicates with the SWIFT interface forversions of QuickSim II prior to the D.1 release. If you are using a version of QuickSimII prior to D.1, you must install the Mentor Graphics application software for eachMentor Graphics user tree.AttentionBeginning with version D.1 of QuickSim II, Mentor Graphics assumedresponsibility for their integration of the SWIFT interface. If you are usingversion D.1 or higher, refer to the Mentor Graphics documentation forinformation about using SWIFT.October 6, 2003 Synopsys, Inc. 125
