ATTRIBUTE command for parts in another sheet

jpieper

I'm working on a ULP for which I would like to set an attribute on parts spread across multiple sheets.  I've run into a problem, where I can't figure out how to set any attributes on parts which are present on anything but the currently active sheet.

 

The problem also appears just writing commands in the editor.  If you do.

 

ATTRIBUTE C10 ATTNAME 'stuff'

 

If C10 is on the current sheet it works, otherwise a dialog pops up that reports: Invalid part or gate name 'C10'.

 

If you first switch to the correct sheet, all works as expected.

 

Is there a way to reference parts in another sheet?

 

Thanks.

  • This is my main gripe with EAGLE, the way you process selected groups or separate schematic sheets.  It's inverted from the way I want to do it.  Instead of having a selection and searching for the sheet it's on, you have each sheet and you have to search for the selection on that sheet...

     

    I think you'll have to loop through all sheets:

     

    schematic (S) {

      sheet(SH) {

        # generate script command to edit sheet.  Something like: sprintf(line, "edit .s%d;\n", SH.number); script += line;

        # look for part

        # generate attribute command for part

      }

    }

     

    Unless you want to start accessing the XML directly...

    Thanks!  With eagle 6.5, I am not having a problem getting the name of all the parts across all schematics, I just don't seem to be able to figure out what attribute command to generate which will allow me to set them.  In 6.5, I'm using SCH.parts(P) { ... } which does seem to list all the parts across all sheets correctly.

     

    Hmmm, maybe it would be easier for me to mess with the XML directly.

    OK, that clarifies a bit for me.  You might want to use the instances() loop of the part where you can find the sheet variable.  I haven't actually tested it, but I think you'll still have to have a pair of commands for each attribute:

     

    switch to the particular sheet  ("edit .s1;", "edit .s2;", etc)

    set the attribute of the part on that sheet
