    mask to mask DRC (stacked blind vias) Reply

     Hello all,
    In Allegro V.15.1, I have a top thru layer 8 blind via and layer 13 thru 20 blind via stacked over one another.
    I also have Soldermask to soldermask spacing set in Constraint / Design Constraint set to 4 mil spacing.
    No bottom mask set in top blind via and visa-versa.

    PROBLEM: I am getting a DRC (M/M) from top blind mask to bottom blind mask.
     But not in top / bottom smt parts on top of one another.

    Any sugestions?

    Thanks,
    Mark

    there has been a service request submitted 33054124 which identifies the problem and requests a fix. Cadence has apparently fixed this, but it has yet to be implemented
