There's been so much unwarranted (IMHO) skepticism
about the ability to
transfer
a solid DEC CPU design into CPLD/FPGA that I'd
really like to see
someone try
it. The DEC folks didn't often do the wierd things
that make circuits
act
There are several PDP-8s outther on FPGAs and there is nothing to say
others would
not be doable save for maybe enough gates (CPLDs) to do the job.
fix the older designs so they'd work fine in
current technology, and
probably
MUCH faster. I'm not interested in DEC stuff
myself, but the fact that

Potential for speed is definately there using newer technology.

Well most of them are doing it from DEC mask sets under license. I

you mean Alpha and PDP-11 (11/93 class).

entered, simulated,
synthesized, simulated and tested as implemented, there's room for
fixes. The
If you dont simulate and test the sim you will likely fail.
