ADE(GUI) DC analysis query

Hello experts, I have one basic query regarding dc sweep analysis done using ADE (GUI mode). The query is whether we can give an expression in the start-stop section of the sweep range? The expression will evaluate to a numerical value.I want to change the range based on the numerical value of another variable. Thanks, Pramod

     Hi Pramod,

     at least for AC analysis you can use variables in this way: VAR("yourvariable"). 

     Best regards,
    Dirk

    Dirk,

    That's true if you are using IC61. If using IC5141, you cannot use the VAR()
    syntax, and these particular fields do no accept non-numerical values.

    So the workaround would be to specify the analysis via an include file. Put the
    spectre statement in a text file, with something like this:

    dc dc param=temp start=startVal stop=stopVal step=stepVal annotate=status

    Add it to your "Model Libraries" (as good as anywhere else) and then define
    design variables startVal, stopVal, and stepVal.

    Best Regards,

    Andrew.
