    Hi there,

    Hi have to check if into a layout hierarchy a certain bBox are cells
    of a specific lib/cell/view

    So I try something like:
    dbProduceOverlapInst(cv myBox 0:32)
    then flatten the returned list and search for insts in the list if
    there are insts with specific lib/cell/view
    The problem is that if I have array of instances (mosaics) they are
    not returned by dbProduceOverlapInst(...)

    I've just made a basic test in a cv I have one inst + one mosaic on
    the same lib/cell/view .
    I've noticed that dbProduceOverlapInst(cv cv->bBox 0:32) returns only
    the instance but not the mosaic.

    Any idea about how can I get also the mosaics ?

    Thank you,
    Marcel

    Hi Marcel,

    Without thinking about it or trying, I think you might need dbProduceOverlap.

    Hi Andrew,


    dbProduceOverlap is looking for the shapes for a certain layer.
    So I request a layer that for sure exists in my lib/cell/view it also
    returns the mosaics :)

    Seems to be a little bit slower than dbProduceOverlapInst, but it is
    working.

    Thanks a lot,
    Marcel
