extract min and max over corners for every variable step

skylink

Hi Everyone, hi Andrew,

With ADE-XL I would like to run a simulation over multiple variables values + over multiple corners.
For instance in global variables:
VAR1 = from/step/to 1/0.1/10
VAR2 = from/step/to 5/0.2/20
...
+each one over the corners: C1,C2,C3,...

I would like to automatically extract the min and max values over all corners, for each variable step,
and after that automatically plot these min and max values for each variable step. The bonus would be to extract the min and max values and use them to chain other simulations.
On the whole, I would like to make an extract among all corners, as if a multiple corner simulation (for each variable step) were a single simulation.

Could you please explain to me how to do?

Thanks a lot in advance!

    You can have an expression using ymin or ymax (of whatever you are trying to measure, perhaps using calcVal() if that's already been measured for each individual point) and then in the "EvalType" column for that ymin/ymax expression set the EvalType to "corners" rather than "point". This will then do these as measurements over corners, and you'll get one value per sweep point.

    You can then reference these outputs using calcVal in some other test.

    You might want to look at this Rapid Adoption Kit: Techniques for Simulating Calibrated Circuits with Virtuoso ADE Assembler (it focuses on Assembler, but many of the approaches would work with ADE XL too).

    Regards,

    Andrew.

    Thanks a lot Andrew, I did not know the "corner" tip; that works fine for me !

    Have a nice Xmas break.
