Simulation using SKILL

deepshah

 hi,

I am simulating a circuit block with SKILL

I wrote Desvar.il, mystimuli.scs, Simsetup.il but i do not know how to proceed with main simulation body can anybody help me?

i want power data to be displayed 

Thanks

  • Hi Deep,

    Aside from the typos ("lost" in SimSetup.il and, "vsouce" in mystimuli.scs) it looks as though you have some pieces of the puzzle.

    You just need the core of the OCEAN script now, something like:

    ;; load the intialization code and call it
    load("SimSetup.il")
    SimSetup = LogTestSetup()

    ;; setup a simulation session using OCEAN commands
    simulator( 'spectre )
    design( SimSetup->LibName SimSetup->CellName SimSetup->ViewName)
    resultsDir( SimSetup->ResultsDir )

    load( SimSetup->VariablesFile )

    analysis('tran ?stop SimSetup->SimStop )
    run()

     

    The main problem I see is that the design does not appear to be parameterized with Twwid, Twper, A1, A2 etc. I would expect to see a "parameters" statement in the spectre netlist which declares them, and later on actually see them being used in place of fixed values, e.g.
     width=Twwid period=Twper

    You may also want to perform your own sort of sweep or parametric analysis, e.g. use a for() or a foreach() looping construct to iterate over different values of one or more parameters.

    I hope that the above helps.

    Regards,

    Lawrence.
