rename net via skill?

danmc91

Is there a convenient way in skill to rename a net?  For example:

mynets=setof(x cv~>nets x~>name=="VDD!")

foreach(net mynets

  the_missing_rename_net_function(net "VDD")  ;; is there such a function?

)

Thanks

    You can't get the pin that way (because you can't guarantee it will be the third instance). Anyway, the trick here is to update the terminal. Because the terminal name can't be updated to a different width, you need to recreate it. This code will do that:

    cv=geGetEditCellView()
    term=dbFindTermByName(cv "RD<7:0>")
    pinFigs=foreach(mapcan pin term~>pins pin~>figs)
    newNet=dbMakeNet(cv "RD<31:0>")
    foreach(pinFig pinFigs
      dbSubFigFromPin(pinFig~>pin pinFig)
      dbCreatePin(newNet pinFig)
    )
    ; dbDeleteObject(term)
    schCheck(cv)

    What this does is find all the pin figures associated with pins on the original terminal name, and then pulls them off the old pin and creates a new pin associated with the new wider net.

    The dbDeleteObject isn't really necessary because the schCheck will clean up any terminals that aren't used any more (so I commented it out).
