Eagle Command Line Name for Net

romaindelamea

Hi !

 

I'm looking for a command line to name a Net.

 

To name a part, I write "NAME OLD_NAME NEW_NAME (for example : NAME IC1 UC, IC1 is the name automatically given and UC the new name I want.

 

But this command does't work with NET. When I write NAME N$1 SPI_CS to name the NET N$1 "SPI_CS" I get an error : Eagle doesn't know the part N$1 !

 

I've tried with command "NAME 'NET: N$1 SPI_CS" ('NET: N$1 is wrote on the bottom of the eagle windows) but it doesn't work too image

 

Does anybody has an idea of what command use ?

 

Tank's for answer and have a good day !

 

Romain.

 

PS : Sorry for my bad English, I'm a french user image

    Hi Romain,

     

    Yes you can't use the NET command in that way although you can work around it with a simple ULP.

     

    Copy the following into a file called nameNet.ulp and put it into your ULP folder:

     

    // Define variables
string cmd="SET CONFIRM YES; ";

if (schematic) {
   schematic(S) {
      S.sheets(SH) {
         SH.nets(N) {
            string tmp;
            if (N.name == argv[1]) {
               N.segments(SEG) {
                  SEG.wires(W) {
                     sprintf(tmp, "NAME %s (%fin %fin);", argv[2],u2inch(W.x1),u2inch(W.y1));
                     cmd += tmp;
                  }
               }
            }
         }
      }
   }
}

cmd += "SET CONFIRM OFF;";
exit(cmd);

     

    now issue the following command:

     

    run nameNet OLD_NAME NEW_NAME

     

    You should find that your net gets renamed throughout your schematic.

     

    Please note: I have NOT fully tested this and it is to be used completely at your own risk.

     

    Best Regards,

                         sprintf(tmp, "NAME %s (%f %f);", argv[2],u2inch(W.x1),u2inch(W.y1));

     

    one small modification here. You either need to make sure your grid

    setting matches the coordinate conversion function, or use explicit

    units in your coordinate formating.

     

    Something linke:

     

    :  sprintf(tmp, "NAME %s (%fin %fin);", argv[2],u2inch(W.x1),u2inch(W.y1));

     

    or

     

    :  sprintf(tmp, "NAME %s (%fmic %fmic);", argv[2],u2mic(W.x1),u2mic(W.y1));

    Hi Lorenz,

     

    Yes that's a good point! I didn't bother checking as I only ever use inches

    in schematics but yes, using the explicit units in the coordinate

    formatting is the correct thing to do. Thanks for pointing this out.

     

    Best Regards,

    P.S. Sorry for the messed up code presentation on NNTP / EAGLE Central, I

    posted my original reply on Element14 and it seems code sections don't come

    over to these places well at all....
