"WebThis BCD counter uses d-type flip-flops, and this particular design is a 4-bit BCD counter with an AND gate. 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 ...

WebVerilog Ripple Counter. A ripple counter is an asynchronous counter in which the preceding flop's output clocks all the flops except the first. Asynchronous means all the elements of the circuits do not have a common clock. For example, a 4 bit counter will count from 0000 to 1111.
