Open Simulation System (OSS) gives you quick access to the simulators that it supports and lets you integrate and customize new simulators into the Virtuoso design environment.

This topic describes the following SKILL functions associated with OSS:

• FNL Functions - The following functions are the flat netlister (FNL) SKILL functions.

• SE Graphics Functions - The following functions, which are defined by SE, simplify integrating your simulator into the Cadence graphics environment. These functions represent the functionality available on the Simulation menu. If you want to create your own menus and/or forms for the Simulation user interface, you can use them to perform the required SE functionality.
  These functions are defined only in the Cadence graphics environment and cannot be executed in the SI program.
  

  simCleanRun	simEditFileWithName
  simInitEnv	simInitEnvWithArgs
  simJobMonitor	simPostNameConvert
  simPreNameConvert	simRunNetAndSim
  simRunNetAndSimWithArgs	simRunNetAndSimWithCmd

  iseEnterNodeNamesList	iseExitSimulator
  iseGetExtName	iseGetInputFromEncapWindow
  iseGetMappedProbeList	iseGetProbeList
  iseInitSchematicWindow	iseInitSimWindow
  iseInterruptSimulator	iseNetExtNameCdsName
  iseOpenWindows	isePrintName
  isePrintNameCB	isePrintSimulatorCommand
  iseReleaseNodeFrom	iseSearchForASchWindow
  iseSendOutputToEncapHistory	iseSetEncapBindKeys
  iseSetNodeTo	iseSimulate
  iseStartInteractive	iseStartSimulator
  iseUpdateNetlist	iseUpdateStimulus

• HNL Access Functions - The following functions include the property, database, and print SKILL functions of the Hierarchical Netlister (HNL).
  • Property functions can be used to search for properties and to scale property values.
    

    hnlEMHGetDigitaGlobalNets	hnlEMHGetDigitalNetlistFileName
    hnlEMHSetVerbosityLevel	hnlGetCellHdbProps
    hnlGetInstanceCount	hnlGetPropVal
    hnlGetRoundProp	hnlGetScaleCapacitance
    hnlGetScaleMarginalDelay	hnlGetScaleTimeUnit

    hnlGetSourceFileModels	hnlGetSymbolPropVal
    hnlOpenTopCell	hnlPcellIsParamOverridden
    hnlScaleCapacitance	hnlScaleMarginalDelay
    hnlScaleTimeUnit

  • Database functions provide information about the design and the internal data structures of HNL specific to netlisting.
    

    hnlAddExtraParameters	hnlCellExtracted
    hnlCellInAllCells	hnlIgnoreTerm
    hnlIsAPatchCord	hnlIsAStoppingCell
    hnlIsCurrentInstStopping	hnlMultipleCells
    hnlNameOfSignal	hnlNetNameOnTerm
    hnlNetNameOnTermName

  • Print functions control netlist formatting and printing.
    

    hnlCompletePrint	hnlInitPrint
    hnlPrintString

• Miscellaneous Functions - The following functions include the general utility functions in HNL.
  

  hnlAbortNetlist	hnlDoInstBased
  hnlFindAllCells	hnlGetPrintLinePrefix
  hnlIfNoProcedure	hnlPrintDevices
  hnlPrintMessage	hnlPrintNetlist
  hnlRunNetlister	hnlSetDef
  hnlSetPrintLinePrefix	hnlSetPseudoTermDir
  hnlSetVars	hnlSortTerms
  hnlSortTermsToNets	hnlStartNetlist
  hnlStopNetlist	hnlStringToList

  • Name-mapping functions implement the name-mapping feature of HNL. You can use the hnlMapName, hnlMapNetName, hnlMapTermName, hnlMapInstName, and hnlMapModelName functions during netlisting. The initialization and write functions are called by the HNL driver as part of the netlisting process.
    

    hnlGetMappedInstNames	hnlGetMappedModelNames
    hnlGetMappedNames	hnlGetMappedNetNames
    hnlInitMap	hnlIsCVInUserStopCVList
    hnlMapInstName	hnlMapModelName
    hnlMapName	hnlMapNetName
    hnlMapTermName	hnlNmpSetNameSpaces
    hnlSetMappingType	hnlWriteMap

  • Incremental netlisting functions can be used when you write an incremental netlist formatter.
    

    hnlCatIncrementalNetlistFiles	hnlCloseCellFiles
    hnlGenIncludeFile	hnlGetGlobalModelMappedName
    hnlGetGlobalNetMappedName	hnlMakeNetlistFileName
    hnlMapCellModuleName	hnlMapCellName
    hnlSetCellFiles	hnlWriteBlockControlFile

• HNL Trigger Functions for Pre- and Post-Netlist Customization - Pre-netlist triggers are called after the .simrc file is loaded and before the netlisting starts. These triggers must be defined and registered in the .simrc file. Post-netlist triggers are called after netlisting finishes and can be defined and registered in the libInit.il file. To maintain consistency, all trigger functions must be defined and registered in the .simrc file. Additionally, a trigger must be defined before it is registered or deregistered. These functions let you customize the netlist as per user requirements after the netlisting is done by the tool.
  The following HNL functions are available for customizing the netlist as per user requirements after the netlisting is done by the tool.
  

  hnlDeRegPostNetlistTrigger	hnlDeRegPreNetlistTrigger
  hnlPostNetlistTriggerList	hnlPreNetlistTriggerList
  hnlRegPostNetlistTrigger	hnlRegPreNetlistTrigger
  simDeRegPostNetlistTrigger	simDeRegPreNetlistTrigger
  simPostNetlistTriggerList	simPreNetlistTriggerList
  simRegPostNetlistTrigger	simRegPreNetlistTrigger

• HNL Net-Based Netlisting Functions - The following HNL functions are available for use by the formatter for net-based netlisting.
  

  hnlCloseMasterList	hnlDoNetBased
  hnlFindAllInstInCell	hnlGetMasterCells
  hnlGetTermByName	hnlGetTermNameOfSig
  hnlIsCellNetlistable	hnlPrintSignal
