Not a bad idea.
The process of reverse engineering a netlist from a
photomicrograph
of an IC is not that far from reverse engineering it from a PCB. Where
you'll run into problems is when the traces run underneath the chips (I'm
assuming you're not i nterested in stripping the boards bare for this).
The boards are low density and have components on a single side only.
So I might be able to image traces under chips with appropriate
lighting and camera angles to show the traces. At any rate, I didn't
expect the tools to be fully automatic, but just assisting with some
of the drudgery.
It's worth automating this task within a reasonable amount of effort
because I have probalby 15 or so boards to go over.
After you've got a netlist, of course, you'll
have to do quite a bit
of manua l cleanup to make any resulting schematic (or textual netlist)
human-readable, including both naming the nets and arranging them in an
order that makes sense.
Yep, that was always assumed. I just want to see if I can get
something basic from the images before I start incrementally improving
the schematic.
