Finding VDC() of a selected net

jorankin
Hello,

I am using cadence icfb version 6.1.4.500.5

I am trying to do the following in SKILL code:

1. After a net is selected, find the DC voltage of that net.

   One would think this is easy by doing the following:

hierInfo=geGetInstHier(hiGetCurrentWindow())

SSN=geGetSelSet()~>net~>name

    name=strcat(hierInfo “/” SSN)

VDC(name)

But this doesn't always work, notably when a net is brought out a level or more of hierarchy than the current window you are in.

Thanks,
John

    Hi John,

    geGetAdjustedPath() is the function you want.

    An example of this in use is in my solution http://support.cadence.com/wps/mypoc/cos?uri=deeplinkmin:ViewSolution;solutionNumber=11021500

    Andrew,

    The help for "geGetAdjustedPath" says that it only "Reduces the given hierarchical net path to the shortest hierarchical name that is equivalent to this net." What I want is what the calculator would give me if I were to probe the net. So I'm not sure this is the right function.

    I  tried it out by doing:

    geGetAdjustedPath(hiGetCurrentWindow() geGetSelSet()~>net~>name)

    I get the following back:

    "dc_test_lowlevel<6>"

    But when I use the calculator, the following appears:

    VDC("/I0/dctest_highlevel<6> ")

    This is because the highest level that this net appears is at I0/, and within I0, this net is called dctest_highlevel<6> whereas at the level I actually probe this net, the name if the net is dc_test_lowlevel<6>. What I want is what the calculator gives me, but I haven't been able to find anything that gives me this information.

    Thanks,

    John

    Hi John,

    It is the right function, but you need to give the full hierarchical path as the second argument and it will reduce it. It has to be a "rooted" path.

    In the solution I mentioned, there is a function CCSgetHierNetName which does this (I think - I'm on a train so can't see the code right now).

    Or you could use:

    wid=hiGetCurrentWindow()
    geGetAdjustedPath(wid strcat(geGetInstHier(wid) "/" car(geGetSelSet())~>net~>name))

    Regards,

    Andrew
