    Hello,
    We are in the final stages of routing our mixed signal chip using
    Wroute in Silicon Ensemble.We are auto routing both the analog and
    digital content. We are down to less than 20 violations or something.
    Silicon ensemble does not insert double vias till all the violations
    are gone and this is kinda our problem in that we recognize the
    present violations and we consider them to be some bugs of the tool.
    We have around 10000 or so vias which we need to stack up with a
    redundant ( double ) via.
    To solve the bugs is just taking too much time.
    My questions are
    1. Can we port the database out now from SE to another tool to insert
    the double vias.
    2. Is the double via insertion just done for yield purposes ??

    thanks in advance
    sachin
