    Hi, GURUs
    I'm using IC5.10.41 VXL. Is it possible to enable/disable abutment for
    separate instances in layout?
    E.g.: Cascode current sources has several devices in parallel. VXL
    abutment works so, that "middle" contacts are removed. LVS reports
    device/net mismatch. Via Propagate Nets form I change instance drain
    connectivity from, e.g. a26_StrongGroup_2 to a26. Then abutment
    occurs, but contacts and metals remain and I can connect them
    correctly. LVS - clean! There are hundreds of devices. Using propagate
    nets form is time consuming.
    Questions:
    1. Is it possible to enable/disable abutment for seperate instances?
    2. How to change ..._StrongGroup_... nets to just normal names, e.g.
    a26_StrongGroup_2 -> a26?

    Thank you
    Edi
