If you search the archives, you can find Chad's F6 CPLD code, that helped
me leaps and bounds set up a delay in my bankswitch code. However some
CPLD's are finicky about it, and you may have to skip generating a timing
report because the CPLD software may get flustered at exactly what is taking
place.
