Essential hazards in CPLD's?

Oct 31, 2003 3 Replies

Hi NG, are essential hazards avoided in CPLD-designs?



If for example I were to design a counter with a subsequent comparator in a CPLD, would I be sure that I got no glitches in the output from my comparator? Or would I have to filter the output before I used it in other part of the CPLD?

They can be.

If you use synchronous design and do static timing analysis, your outputs won't glitch.

I thought so... :-/

Ah... Of course... Only problem is that I guess this requires a higher macro-cell count and my current design is already at the limit (and there are many counters in it :-)).

I guess this is the best/"cheapest" way to do it. Thank you for the info.

Best regards Preben
