How to check if a net has a probe on it?

Runner

Hello!

I want to find out if a wire (I have it's data base Id) has a probe on it and probe name. Net's name may differ from the name at top-level schematic.And, of course, using SKILL. (icfb 5.10.41)

Thank you.

    Have you found any solution on this?

    I am trying to find all the terminals a net connects to through the hierarchy (both up and down).

    AddNetProbe give this functionality but there doesn't seem to be a away to find out through SKILL if a net has a probe on it.

    Using IC 6.1.

    Thanks,

    Kostas

    Kostas,

    There will be a "probes" assistant in IC616 (currently due Q2 2013) which will tell you this level of information. I don't think you can extract it from a probe right now - you'd have to trace the nets yourself (which is a non-trivial amount of work).

    Regards,

    Andrew.

    Yes, e.g. to obtain the name of the nets with probes:

     probes = geGetAllProbe()

    probe_types = probes ~>probeType

    nets = probes~>pathObjectName

    And then you can use function geGetAdjustedPath(win net_name) to obtain the name of the the net with net_name at the highest level of hierarchy. If two nets have the same root net, they are the same net.

    That doesn't help much - if I add a probe at the top level, and then descend into a block, the pathObjectName is the top level name - so it doesn't tell you what the name in this cellView is.

    Actually, it helps and there is answer in my post - you have to derive root name for each net in the cell and compare it with root name of the net at different level (where you placed the probe).
