Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys Models●VendorEach subfunction menu item has an associated vendor menu that lists the partmanufacturers for that group of models.●PartEach vendor menu item has an associated part menu that lists all available DWMMmodels and SmartModels.●ComponentEach part menu items has an associated component menu that lists the timing and/orsymbol versions for a particular model.ExampleThe following sequence of menu selections would select timing version “10” of theDWMM model of the Cypress cy7c199:SmartModel Library > Memories > SRAM > CYPRESS > CY7C199-10 > 10Building a Design Without the MenusIf you are familiar with the SmartModel Library, you may prefer to use SchematicEditor commands to build designs. This can be faster than using the menu system.The basic steps are essentially the same:1. Identify the model you need.2. Instantiate the model’s symbol on the schematic sheet.3. Use Design Architect or the Schematic Editor to edit property values if needed.Creating An InstanceUse the $add_instance command to instantiate a part in the Schematic Editor, as shownin the following minimal command:$add_instance ("$LMC_HOME/special/qsim/symbols/model_name")You can also include the DWMM symbol properties on the same line, as in theseexamples (all punctuation marks are required):●Example of defining a single property:$add_instance ("$LMC_HOME/special/qsim/symbols/model_name",,,,["property_name","property_value"])October 6, 2003 Synopsys, Inc. 157
