Orcad Capture 17.2 TCL & Symbol creation.

excellon1

Hi, I was wondering is it possible to use TCL in orcad capture when creating symbols.

Specifically what I want to accomplish is the addition of attributes to symbols by automating the process.

When I create a symbol I like to pre-load the symbol with attributes so that I can generate a meaningful BOM and or make a schematic more legible. For example on my schematics I include the PCB Footprint value on each symbol so a engineer can see at a glance what PCB Footprint is assigned to that particular symbol. I also have additional attributes that would be geared to the bom such as P/N, MFR PN etc but these typically remain hidden.

Thus far doing this has been a highly manual operation that I am trying to automate and was thinking TCL may just be the answer.

If anyone has any insight on this it would be very helpful. I had looked over the TCL Documentation but it seemed more geared to the schematic than physically creating symbols.

Thanks.

  • Yes. You can use Tcl to create symbol or add additional properties. Here is a sample script to add a new property

    You can add new property on symbol using following tcl commands:-

     

    # [Assuming you have object of DboLibPart  ($lPart) ]

    set mStatus [DboState]

    set lPropName [DboTclHelper_sMakeCString {Description}]

    set pLocation [DboTclHelper_sMakeCPoint 40 60]

    set pFont [DboTclHelper_sMakeLOGFONT {Description} 8 0 0 0 400 0 0 0 0 7 0 1 16]

    set mProp [$lPart NewDisplayProp $mStatus $lPropName $pLocation 0 $pFont 48]

    $mProp SetHorizontalTextJustification 0

     

    There is no direct API through which you can move the Display property but you can change the location of Display Property using following tcl commands:-

    # [Assuming you have object of DboLibPart  ($lPart) ]

    set mStatus [DboState]

    set lPropName [DboTclHelper_sMakeCString {Part Reference}]

    set lDisplayProp [$lPart GetDisplayProp $lPropName $mStatus]

    $lDisplayProp SetLocation [DboTclHelper_sMakeCPoint 100 100]
