Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys ModelsTable 14: Symbol Properties Required for Simulation (Continued)PropertyDescriptionPKGEach model has a PKG property equal to thephysical package type (for example, DIP, LCC) thatthe symbol's pin numbers match. When using thebus symbol for a component, the PKG property isset to the value “BUS”.Optional Symbol PropertiesTable 15 lists optional symbol properties.Table 15: Optional Symbol PropertiesPropertyCOMPPIN_NAMEPIN_NOREFDescriptionThe COMP property provides an interface to layoutor other applications. Synopsys does not use thisproperty.The COMP property is assigned the default value“TimingVersion” with the property attribute“expression”. This causes the COMP property totrack the value of the TimingVersion property forSynopsys symbols.The PIN_NAME property is the visible text on asymbol representing a pin's name. Changing thistext has no effect on the model's operation.The PIN_NO property value matches the physicalpin number of the component for the defaultpackage. Changing the value of this property has noeffect on the model's operation.The REF (reference) property provides an identifierfor use in Advanced Verification messages.Changing the value of this property has no effect onthe model's operation.Building a Design Using the MenusThe Synopsys entries in the Design Architect menu system can be useful when buildinga design for the first time because all of the alternatives at each menu level are apparent.To add SmartModels to a design using the menus, follow these steps:1. Identify the desired model using the Schematic Editor menu system to traverse themenus.October 6, 2003 Synopsys, Inc. 131
