corner variables in adexl

bid75

If I have to add two variables in corner setup of ADEXL, is there a way to specify them as connected like ordered set. For e.g if var1 can take {10 20} and  var2 {0 var1} -- so the net runs {var1 var2} will be {10 0} {20 0} {10 10} {20 20} -- sometimes more complicated sets are required where we need to explicity specify the set of {var1 var2} as some combinations are invalid and should be pruned.

Thanks

    Hi Bhavin,

    You can't use variables in the sweep limits, but you could enter:

    var1: 10 20 10 20
    var2: 0 0 10 20

    Then select both variables and do Right Mouse->Group as Parametric set. This means it would do {10 0} {20 0} {10 10} {20 20} as it sweeps both lists together.

    You can see this in Run->Run Preview (you have to hit the refresh button) which will show you what is going to be swept.

    If using ADE Assembler, you could also sweep the two variables independently (i.e. no Group as Parametric set, although that is also available in Assembler):

    var1: 10 20
    var2: 0 10 20

    and then on the run preview you have checkboxes so you can disable the combinations  you don't want to run.

    Regards,

    Andrew.

    I don't see the menu item : Right Mouse->Group as Parametric set

    IC6.1.7-64b.500.17

    Surprisingly thres "2 vdd-2" seems to work in sweeps.

    OK, you said sweeps, not corners. I was talking about how to do it from the global variables in the data view assistant. You didn't mention corners...

    Andrew.
