BCD counters usually count up to ten, also otherwise known as MOD 10. Since a 4-bit counter counts from binary 0 0 0 0 to binary 1 1 1 1, which is up to 16, we need a way to stop the count after ten, and we achieve this using an AND gate ...

WebMar 10, 2024 · The output ring is a 4-bit one hot vector, reset_n = 0 makes ring = 0001 every clock with reset_n = 1 rolls the ring to the right, [0001, 0010, 0100, 1000, 0001, ...]. But you want to use instances of the flops you defined. Notice that in an assignment a <= b, a is the output of the flop (q port), and b is the input of the flop (d port). 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.
