Doug,

   IPC-D-356, current revision (-) does NOT provide for "trace data", but if 
your implimentation includes it and it doesn't contaminte the reset of the 
data, keep using it.

   Duane Delfosse, Circuitest, is chairing the IPC-D-356 committee to update
IPC-D-356 to revision A and the new revision will include trace data for 
analysis and repair, the use you stated.

   The new revision will also include allowance for description of buried 
resistors and capacitors as well as hbipot and impedance testing.

   Duane and the IPC office (Lisa Williams) are preparing the new document
for circulation for review...I don't know the exact schedule, but it should 
be out before the first of the the year.

   Please contact Lisa at the IPC office or Duane at Circuitest, 603-882-2621.
or send E-mail to the above addresses.

Regards

Harry Parkinson
General Chair, CAD/CAM Electronic Data Transfer Committee (including IPC-D-356)

Hi all,  

I am looking for some insight into IPC-D-356 files...we use these
netlist files as test programs..most of the time we extract them from
the gerber data as part of the fixture building process and then run
them as the program for the tester..However I have looked at the files
and the format does not exactly match the IPC-D-356 format...there are
extra things in it..with some investigation I have found that the net
list we extract has "trace data" in it to be used by the analyser for
repairs. I cannot find any reference to this "trace data" in the
specification....So...

Does the IPC-D-356 format support trace data or has my net list
extraction software supplier modified the D356 format to include this so
that their analyser will run??

I can say that the first 80 characters of the netlist we use match the
IPC format exactly..however I cannot find any reference to the rest of
the information...

So, if someone could please....HELP??? :)

Thanks
