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.
