Pin numbers in Schematics

Dave schrieb:

The pad name only applies to boards, not schematics.

But it is referenced in the schematic as well (and is also displayed in

the schematic as well, even if there's no board at all).

It must be possible to obtain the pin number, because the in-built netlist

exporter outputs those values as 'pad' in column 3...

 

Can someone explain how to navigate the object hierarchy to get the pin

numbers from the package relating to pinref of the the component in the net

being processed here:

I'm pretty sure it is possible, but I'm not used to writing ULPs...

Perhaps you have a look at the following object hierarchy:

- UL_SCHEMATIC has a loop member named "part", of type UL_PART

- UL_PART has a loop member named "device", of type UL_DEVICE

- UL_DEVICE has a loop member named "gates", of type UL_GATE

- UL_GATE has a data member named "symbol", of type UL_SYMBOL

- UL_SYMBOL has a loop member named "pins", of type UL_PIN

- UL_PIN has a data member named "contacts", of type UL_CONTACT

- UL_CONTACT has a data member named "pad", of type UL_PAD

- UL_PAD has a data member named "name", of type string

- UL_PIN also has a data member named "net", of type string,

  as well as a data member named "name", of type string

By following this hierarchy with the appropriate loops and references,

you get all pin/pad/net relations you need.

Tilmann,

Thanks for the help. This now works:

if (schematic) schematic(SCH) {

   output(filesetext(SCH.name, ".NET")) {

   SCH.parts(P) {

     printf("%s\n","[");

     printf("%s\n",P.name);

     printf("%s\n",P.value);

     printf("\n\n\n%s\n","]");

     }

   SCH.nets(N) {

     numeric string Part[], Pad[];

     int cnt = 0, index[];

     N.pinrefs(P) {

       Part[cnt] = P.part.name;

       Pad[cnt] = P.pin.contact.name;

       cnt++;

       }

     if (cnt) {

        sort(cnt, index, Part, Pad);

        printf("%s\n","(");

        printf("%s\n",N.name);

        for (int i = 0; i < cnt; i++)

            printf("%s%s%s\n",Part[index[i]],"-",Pad[index[i]]);

        printf("%s\n",")");

        }

     }

   }

}
