EvalType in Cadence ADEXL

NorNand

Hello,

I read the help documentation of ADEXL couldn't understand what the function of EvalType in the Output Setup of ADEXL interface. Basically it give two options: Point and Corners, by default Cadence set it to Point but what either means to choose the proper selection

Thank you

  • I just searched in the documentation for IC616 (you're using a rather old version), by running cdnshelp from that release and searching for "evalType". I found in the ADE XL manual it describes this:

    4. (Optional) The default value in the EvalType column is point. This signifies that by default the expression will run for the given design point. If you want to run the expression for all corners across the design point, double-click in the EvalType cell and select corners from the pull-down list.

    When you set the EvalType as corners, the color of the row is changed to blue. For more details, refer to Creating Expressions to be Measured Across Corners

    That contains a link to a section about measurement across corners. The idea is that if you pick "corners" the expression works across the entire data for all corners (for that sweep point). It typically would be used with functions such as ymax, ymin, average etc, and will find the max, min, average across the corners. The default of "point" means that it runs the expression for each simulation point separately.

    ADE Assembler extends this concept to support measurement across sweeps and measurement across all (so has "sweeps" and "all" as other evalType choices).

    Andrew.
