I attended a focus group last nught on PLDs and several of the participants
mentioned the AMD MACH series. Their comments were uniformly negative and
centered mainly around a large list of problems with the design software and
attempting to pry information from AMD on how it worked. 

I felt that I should pass this on in case anyone is considering using these
parts.

It was also mentioned that there is a problem with Altera parts. It seems
that the input portion of the pin driver is prone to oscillation (circa 50MHz)
in the presense of slowly changing signals such as tri-stated busses. This
creates noise on the internal power rails and can cause problems even if the
input is not being used.
