Simulator Configuration Guide for Synopsys Models

Chapter 1: Using Synopsys Models with SimulatorsSimulator Configuration GuideTable 5: DesignWare Memory Model SWIFT Parameters (Continued)Parameter Usage Valid Values, Examples, &DefaultsModelAliasThis is the same as the ModelId, except thatyou can use a unique string that is easier foryou to remember than a ModelId integer.The ModelAlias is also handy for logicaladdress mapping. For example, if you hadfour 8-bit memory devices strung togetherin a design, you could alias their modelnames so that you can sequence testbenchcommands to the models correctly:● first_mem●●●second_memthird_memfourth_memValid values are quoted strings.Example: “first_mem”Default: None. If you don’t specifya ModelAlias, this feature isdisabled.Note: The default value in themodel wrapper file is “.”, which justmeans that this feature is off.TimingVersionUse this parameter to specify the timingversion that a model instance uses whenscheduling changes on its outputs orchecking setup and hold times on its inputs.Note: If you set this parameter to “none”,the model operates in function-only mode,with no timing.Valid values are the timing versionssupported by the model, in quotedstrings, or “none”, which specifiesfunction-only model operation.Example: “7A”Default: Timing is on. The defaultspeed-grade is model-specific—seethe model wrapper file.Note: For a list of supportedcomponents or timing versions, seethe individual model datasheets.DelayRangeUse this parameter to specify a propagationdelay range for a model instance.Valid values are “min”, “typ”, and“max.”Example: “TYP”Default: “max”Note: This setting in not casesensitive.30 Synopsys, Inc.
