WebApr 30, 2015 · 3. There's no issue with your connections (they correctly form a ring counter), but you're not going to see much happen. After reset, all of your flip-flops contain zero, which will get circulated around the ring with each clock pulse but never actually cause a change in the outputs. The assignment of a default value of '1' for q3 when you ... 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. WebIn this lab, you will be building a 4-bit counter using RTL Verilog. Use a 4-bit RCA, four 2-1 MUXes, and four D-type flip-flops to implement a 4-bit counter using Verilog The counter should have Reset, Clock and Count inputs. When Reset = 0, regardless of the Count input you should observe all counter outputs to be zero (active-low reset). the place foundry
