Problem with TCL code to change pintype on symbol within a schematic

gvellet

I have imported a schematic from Mentor Pads into Orcad Capture. The discrete symbols created have the wrong pintype and there are a lot of them. For the all discrete  symbol, I need to change the pintype value to "passive". I want to do it using a TCL script. My TCL is able to scan through all the symbol instances, and read the pintype value using the method GetPinType. However when it attempts to change the pintype value with method "SetPinType", nothing happen. I wonder if someone could help me debug my tcl code (See attach zip file)

Thank you

    HI Gvellet.

    SetPinType(pinType) : returns DboState, will not work for the part placed on the schematic. Because on schematic level part/symbol pin type cannot be changed.

    Part can be edited in symbol editor.

    You need edit the part and update current(cache) will work.

    Hope this helps!

    Hi CadAP,

    OK I understand that I have to work on the library then do update current cache in the schematic. Can you help on how to make a script which work on an opened symbol library, it would iteratively edit all the symbols, then iteratively change the pintype of all their pins. Then I will add some intelligence to select only a set of specific symbols.

    Thank you for your time,

    Hi Gvellet,

    I have added below in your script to access the library part to modify it.
    #Convert PartInst to PlacedInst
    set lPlacedInst [DboPartInstToDboPlacedInst $lInst]
    #Get DboLibPart from the Placed Inst
    set lPart [$lPlacedInst GetPart $lStatus]
    set lpinIter [$lPart NewPinsIter $lStatus]
    delete_DboSymbolPinsIter $lpinIter

    Attaching the modified script(pin_test.7z) working to change the pintType.

    You surprised me with a solution that works in the schematic without having to edit the library files.

    Thank you very much.
