16 years agoFSM coding.
Hi everybody, I test the two kinds of FSM on Quartus II: mealy and more, then I check timing analysis on "classic timing analysis" . Anyone explain me why the timing of MOORE FSM is better MEALY F...

16 years agoWith my full respect to Moore & Mealy for their efforts, I have worked over a decade in FPGA design and never needed to to categorise FSM as such.
I design FSM as the logic requires and it may end up with outputs depending on either state only(call it Moore) or state and input(call it Mealy) i.e. probably a mixed Moore Mealy with different proportions... I will be glad if anybody can tell me if this classification is indeed useful in today's sequential design. With regard to timing performance, I believe it is more to do with the design itself than being Moore or Mealy since both need be pipelined correctly.
