I found a strange condition by accident today that DRC fails to detect. We had a part mis-defined with a PAD that was a 'toplayer' pad (not a 'multilayer pad') that had a drill hole defined in it... not on purpose, but by accident.
Now DRC did not pick up any shorts with planes or traces running under this pad but if drilled and plated through in the actual board it would have shorted to the internal layers and any tracks running under it. This happened because somehow we had an unusual condition that the DRC seems to not check for I guess... not seeing any errors on DRC I assumed the board was good. The error was caught by our board manufacturer thank goodness and we corrected the condition. Has anyone ever run across this before? Bill Brooks - KG6VVP PCB Design Engineer, C.I.D.+, C.I.I.
