Hmm. My design is a bit wacky... it's mostly clock-based, but also has
a combinatorial part. I'll test what I have with a real CPLD, see if
it'll
work (or not). Good thing they're erasable, I feel it's not the last
time I'm going to re-write it !
When they said warnings and "your on your own" that means when you make
something
"just barely function" and have no safety margin logically coming form the spec
sheet
of the parts you used, you do not know when it will or won't work, at which
temperature, or on which individual part from the factory.
