Hi Jeffrey,

If you are utilizing Cadence Allegro then you should take a look at the
"Compare" command here under the "Tools" section.  I believe it will do
exactly what you require.

Subject: [DC] Verification of Changes

We are looking to implement a process for verifying the deltas between
revisions of PWB artwork. I have tried a CAM compare of the gerber data
but found that the system we use generates too may delta-points for simple
changes like moving a copper pour outline. I have also tried a data base
comparison using visECAD but it takes far too long to run and generates
cryptic blank boxes with no explanation of what is different. I need a
system/process that will generate a clear report of differences that can
be run in process with engineering change orders, any suggestions?
