I've got a bunch of Nuclear Data peripheral
circuit boards that I need
to reverse engineer. They are simple circuit boards with all the
tracings visible (i.e. no internal layers) and the parts are all 7400
series logic in standard DIP packaging.
If I were to do this manually, I would take high resolution
photographs of both sides of the board. From the photographs, I would
try to recreate engineering drawings: part placement and circuit
topology.
I'm wondering what kind of tools are out there that would assist in
this. Could I process the photos to extract the topology of the
printed circuit traces? Can I correlate this with image recognition
of the part packages and combine them to product a netlist?
Sounds like you need the equivalent of the netlist-extractor portion of
LVS (layout vs. schematic).
