does a reverse-engineering EDA tool exist?

Actually you do, when creating nets from random logic and you don't want to miss the use of any
small logic in a package. I need to look at the spreadsheet methodology used on the Amiga board
trace.

This is the tedious part. Tracing buffers, muxes, decoders is fairly straightforward, it is figuring
out the glue logic that is tedious. It is really easy to lose your place doing it. You end up probing
an output and then sweeping nearby ICs hoping to find something connected.

It's much easier on a bus, where you know the source and there is a high probability it will connect
to a 20 pin buffer or latch somewhere. There is also a pretty high probability these devices will
either be near a microprocessor, or a board connector.
