How to edit dependent expression in ADEXL to represent specified corner sim result ?

sjwprc

Hello, suppose I have run a process corner simulation (FF, SS, TT) to find transconductance of input diff pair. I can define "Gm" as the output name. 

Then I wish to edit expression across corner  to check Gm(FF)-Gm(TT) and Gm(SS)-Gm(TT), how I can edit such expression in output setup ?

    Add an output expression:

    calcVal("Gm" "AC" ?cornerName "FF") - calcVal("Gm" "AC" ?cornerName "TT")

    (note that the test name is "AC" in my case - this is the test where the Gm output is created). Set the "EvalType" column in the ADE XL outputs to be "corners" rather than the default "point" - you'll see the row in the outputs goes a sort of lilac colour when you do this.

    Of course, you can add a second output expression for the difference between SS and TT.

    Regards,

    Andrew.
