  2. O/P logic critical path Ext. O/Ps NS+O/P Logic Ext. I/Ps NS exc. bits State bits FFs NS logic critical path Critical paths in the comb. logic of a Mealy seq. ckt A critical path (max-delay path) in the next-state (NS) logic. Delay is from Q,D,N i/ps to the FF D-ips. Delay = demux delay (3-i/p AND gate delay) + 3-i/p OR gate delay = 6 units A critical path in the o/p) logic for a Mealy m/c. Delay is from Q,D,N i/ps to the ckt o/p(s). Delay = demux delay (3-i/p AND gate delay) + 3-i/p OR gate delay = 6 units Critical path in the o/p) logic for a Moore m/c. Delay is from Q,D,N i/ps to ckt o/p(s). Delay = 0 units as there is no logic reqd in this case
