three types of synchronous designs.
The first type of design is a state machine with feedback
signals sent off-chip. This external feedback could go
back to the device inputs, or to a second device in a
multi-chip state machine. The slowest path defining the
period is the sum of the clock-to-output time and the in-
put setup time for the external signals (t

vice. This f
The second type of design is a single-chip state ma-
chine with internal feedback only. In this case, flip-flop
inputs are defined by the device inputs and flip-flop out-
puts. Under these conditions, the period is limited by the
internal delay from the flip-flop outputs through the inter-
nal feedback and logic to the flip-flop inputs. This f
