Has anyone seen a debugging tool what will provide something that looks like
a logic analyser hooked up to all the IO pins on a PIC (16C74 if it
matters).  I just want to see a computer simulation of all the pins toggling
based exclusively on the program, not on the board or any external inputs.
I could do it 'manualy' by tracing the program flow, but I was hoping there
was a tool out there that does what I am looking for.

Thanks

Shawn
