ADE corner setup: Can I define a parametric set there?

StephanWeber

Hi, in the Data view assistant I can set variables and sweep, but also parametric sets. Can I push such a definition also to the corner setup? Or define a parametric set directly in the corner setup window?

I want to define a special set of combinations:

1. Include ALL extreme combinations like Tmin/Tmax, Vddmin,VDDmax, etc. => 2^n combinations

2. But then add on top also an OFAT3-sweep like Tmin, Ttyp,Tmax with all other vars at nominal + Vddmin/typ/max, and again oll others at nom. => 2*n+1 combinations.

This is something I could also do manually. but the step3 is this:

3. Take these variable combination (2^n+2*n+1) and combine them with process corners, like TT, FF, SS, FS, etc.

Bye Stephan

    And there's a long-standing request (with a growing number of duplicates) asking for native support for paramsets within the corner definition - the master CCR number is 1295169.

    Hi Frank and Andrew,

    my issue with the existing expand as feature is that it leads to huge corner setups because the setup becomes expanded a lot. My target is e.g. to deal with 6 variables, each with 3 values like min, typ, max. And I want from that e.g. all linear 6 linear sweeps, like on T (nim,typ,max) + all others at typical. Already this leads to 2*n+1=13 corners. So your typical corner setup often doubles.

    However, 3 things make it even worse:

    1. Often you also want to use these 13 corners for each process corner (like 5: TT, SS, FF, FS, SF)

    2. Often you need further combinations like all extreme combinations (exclusing Typ, so leading to 2^n further new combinations).

    3. Imagine you created such a big  set of new corners: How would you be able to modify it (e.g. add one value, change a value, or add/remove/rename a variable)? 

    If the selected variables would remain grouped (like possible in Data View Assistant) it would be so much better.

    Note, that ADE has a nice feature already in the WC Corner mode: Here in the setup table you can select different DOE setups like OFAT, OFAT3 or full-factorial. Having this in corner UI for a group of variables is what we need often.

    Stephan,

    This is precisely why the enhancement request exists - others (including me) have reached the same conclusion that keeping the corners grouped yet as a param set would be extremely useful.

    I suggest (if you've not done so already) you contact customer support and request a duplicate be filed.
