I came across some PCBs that use PROMs as state-machines, and am wondering if there is any software that can take the contents of the PROMs to generate a State Diagram or Table of some sort...
Appreciate if anyone can advise on how I can derive a state diagram based on the PROM data. Thanks!

PROM can only generate next logic and output logic for a state machine,
PROM's address is current state input and other input,
PROM's data is next logic and outputs.
you can read PROM's content and convert them into truth table,
perhaps use some logic reduction tool, you can get the logic that
you wanted.
best regards

It is tough, try to use Agilent logic analyzer, to capture the wiveform, then I gues modelsim from Mentor will make you happy
All the best
