D flip flop 4 bit counter verilog

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. Viewed 10k times. 1. I am implementing a 4 bit counter using a D flip flop. For that, I have first written the code of D flip-flop then converted it to T flip-flop and then used it to make a counter. The problem I am facing is that only first instance of T_flipflop "T0" is working while other bits are on unknown state. The output of the code!!

http://web.mit.edu/6.111/www/s2004/LECTURES/l5.pdf 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 ...
