Timing Analysis of Sequential Circuits. Can the following circuit operate reliably? (In other words, is the hold time constraint met?) If so, what is the minimum clock cycle time (Tc) at which it can operate? Also state the maximum frequency (f =1/Tc) at which it can operate. The timing characteristics of the flip-flops are given in Table 2 and the maximum and minimum delays of the combinational logic are stated on the schematics. Recall that 1 picosecond (ps) is 10-12 seconds. (1 nanosecond (ns) is 10-9 seconds, 1 microsecond (μs) is 10-6 seconds, and 1 millisecond (ms) is 10-3 seconds.) see attached.

Latches and Flip Flop

Just like logic gates, the latches and flip-flops are the important elements of an electronic circuit. The logic gates form the important part of combinatorial circuits, while the latches and flip-flops form the essential part of a sequential circuit. Sequential circuits form the important concept of automata theory in electronics and electrical engineering, these circuits are a kind of logic circuit whose output depends on both present input and past inputs, that is, the input history.
