WebDecade 4-bit Synchronous Counter. The additional AND gates detect when the counting sequence reaches “1001”, (Binary 10) and causes flip-flop FF3 to toggle on the next clock pulse. Flip-flop FF0 toggles on every clock pulse. Thus, the count is reset and starts over again at “0000” producing a synchronous decade counter. WebMar 10, 2024 · Few observations: Use only nonblocking assignments to model sequential logic. In the JK Flip Flop, assign qn using a continuous assignment outside the sequential logic block e.g. use assign qn = ~q; so that it correctly reflects the complemented value of the current value of q (not the previous value). qn should represent the complement of q, …
