    Hi,

    Is there any option to select the marked net?

    No. In IC613 you do have RMB->Routing Object Granularity in VLS XL which allows
    you to select all shapes on a net, say. But doing this from Mark Net is not
    supported (Mark Net goes through the hierarchy too, so it wouldn't make much
    sense in that case).

    Regards,

    Andrew.

    hi Andrew,

    My intention is to select a net which doesn't have net name by tracing
    the connectivity.can you give some idea how to start coding for this?
    I was able to trace the connectivity of metal1 till poly and metal2
    but not able to continue further. stucked with looping further.

    I tend to use lxHierExtract() when I want to do this - use part of Virtuoso XL's
    functionality, rather than reinventing the wheel.

    Or use an extraction tool (e.g. Diva, Assura, Calibre etc).

    You can do the following with SKILL, but it can get quite complicated, and quite
    hard to implement efficiently. Don't have time to outline a full algorithm for you.

    Why are you trying to do this?

    Andrew.
