does a reverse-engineering EDA tool exist?

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.
