Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 1: Using Synopsys Models with SimulatorsUsing FlexModels with SWIFT SimulatorsRegardless of which simulator you are using, you must configure FlexModels bydefining the required SWIFT parameters or attributes shown in Table 3 for eachFlexModel instance in your design. You configure FlexModels when you instantiatethem in your design using these SWIFT parameters. This could take the form of Verilogdefparams, VHDL generics, or symbol properties, depending on the simulator you areusing.Table 3: FlexModel SWIFT ParametersParameter a Data Type DescriptionFlexTimingModeFLEX_TIMING_MODE_OFF(default)FLEX_TIMING_MODE_ONFLEX_TIMING_MODE_CYCLEDisables/enables timing simulation.(For Verilog, prepend a back quote(‘) to the constant.)Note: C-only Command Mode userscan set this parameter to:- “0” for timing mode off- “1” for timing mode on- “2” for cycle-based timingTimingVersion Model timing version The FlexModel timing version. Referto the individual FlexModeldatasheets for available timingversions.DelayRange “MIN”, “TYP”, “MAX” (default) If you set FlexTimingMode to on,you can select MIN, TYP, or MAXdelay values with this parameter.FlexModelId “instance_name” A unique name that identifies eachFlexModel instance. This name isalso used by the flex_get_inst_handlecommand to get an integer instancehandle.Note: Used only with _fx modelsFlexModelId_cmd_stream “instance_name” A unique name that identifies eachFlexModel instance or commandstream. This name is also used by theflex_get_inst_handle command toget an integer instance handle. Forinformation on cmd_stream names,refer to the individual FlexModeldatasheets.Note: Used only with _fz models.October 6, 2003 Synopsys, Inc. 23
