'[PIC] - Debugging Tool Request'

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

UMPS (http://www.vmdesign.com) will do the Job perfectly, even will print the graph
of your digital output, but not for 16C74, today UMPS can simulate a reduced
part of the PIC:

PIC16C52,54 C55 C56 C57 C58, C84 F84 F83
PIC16C71, PIC16C710, PIC16C711, PIC12C672, PIC12C671,
PIC16C554, C556, C558, PIC12C508, PIC12C509,
PIC16C620, 621, 622

Regards,
       Philippe.

Phillipe,

Thanks for the input, but I need something that will do one of the 40 pin
packages.  I am not using any of the high end features (AD, SPI etc), but I
do need to monitor all 33 of the IO pins.
