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

  • Andrew,

           Ok yeh this worked. Thanks a lot!
