Stacked Via Constraint Control (Performance L Option)

CCR77

Hello,

       I am currently working on a design that shall utilize stacked micro vias from 1 to 4 with a buried mechanical from 4 to 5 followed by stacked micro vias from 5 to 8.  We cannot stack on the buried mechanical from Layer 4 to 5 and the micro's must be offset from it.  Is it possible to adjust the constraint manager to allow the micro's to be stacked and only apply the offset to the mechanical with the Performance L Option? 

       When I adjust the Min BB Via stagger value it applies the offset to the entire stack.  When I created the padstacks for the vias I checked the radio button for Micro Via's and did not for the burried mechanical. I was hoping this was a flag to the CM but I assume it is not. Any help would be appreciated.

Thanks,

Clint

    Hi Boma,

                You are correct.  My team purchased performance L licenses, however I have access to XL licenses if they are not needed by another group.  I quickly tested with XL and it works as you suggested, the issue is that I dont have priority with the XL editor and could be requested to drop it any time....  :(

    Thanks,

    Clint
