Find missing SilkScreen RefDes on board design

TiBo

Hi,

Is anyone knows how to find a missing REFDES on silkscreen or assembly layer? Is there a skill code to do that?

From time to time I find a few part on the design missing REFDES, probably they got deleted by accident and I didn't even know about it. It takes a lot of time to check each part on the board. If there are a better way to do this, please do tell.

Thank in advance.

Regard,

TiBo

    Try something like this:

    layerPrefix = "REF DES/SILKSCREEN_"
    setof(sym, axlDBGetDesign() ->symbols, sym ->refdes && !exists(obj, sym ->children, obj ->text == sym ->refdes && index(obj ->layer, layerPrefix))) ~>refdes

    Thank Dave,

    Please excuse me for lacking of knowledge of skill code.

    Could you be kind to show me how this work?

    Thank again.

    Dave,


    THAT was pretty nice. Thanks for sharing.


    TiBo,

    To use, type "skill" at the Allegro command line (no quotes). Then type or paste the next two lines on the Skill command line. Type "exit" to get out of the Skill environment (no quotes).

    Thank so much Dave and Kory.

    Can you put this in a xxxx.il file so we can query with one click ?

    Thanks

    Hi TiBo,

    I put Dave's routine in the format required for Skill to run.  Unfortunately, I couldn't see how to attach a file to the post, so I am including it in this message.  Save the area between "### begin Skill code" and "### end Skill code" to a file called findMissingRefdes.il.  Then, you can load it as you would normally load a Skill program.  To run it, you just type "fmr" (no quotes) at the Allegro command line.

    ### begin Skill code

    ;------------------------------------------------------------------------------
    ; FMR skill routine ver. 0.1
    ;

    procedure( find_missing_refdes()

    layerPrefix = "REF DES/SILKSCREEN_"
    list = setof(sym, axlDBGetDesign() ->symbols, sym ->refdes && !exists(obj, sym ->children, obj ->text == sym ->refdes && index(obj ->layer, layerPrefix))) ~>refdes

    print(list)

    );procedure


    axlCmdRegister("fmr" 'find_missing_refdes)

    ### end Skill code
