At the time of reset the value of the counter is initialized to, say, 0. It then becomes 0. Basically there is one bit that keeps shifting to left 1 bit at each clock cycle and then it rolls over when it reaches MSB. Here is the verilog implemmentation of ring counter. Notice the blocking assignment a0lt a3 endassign q a endmodule. Verilog Code For Shift Register Serial In Parallel Out' title='Verilog Code For Shift Register Serial In Parallel Out' />At the time of reset we make the ring counter to start at 4b. When it comes out of reset, we use two statements to update the ring counter at each cycle. Notice the blocking assignment. Notice that we have used non blocking assignment and not blocking assignment. You can think of it as follows. Just before the clock cycle, mentally calculate alt lt 1 in a temporary register. Also mentally assign a0 the value. BEFORE the execution of the alt lt 1. Now at the rising edge of the clock the two assignmenta take place. For example let us say current value of a is 0. The the left shift assignment will shift it to 0. The a0 lt a3 will. Now when the value of the a is 1. The left shift alt lt 1 assignment is tending to make a to 4b. But remember, we have used non blocking assignment. So the next non blocking statement a0 lt a3 takes effect. This statememt. takes the value of a3 which is 1b. Now mentally store is in your mind and at the next clock cycle assign it to a0. If, however, you use blocking assignment staatements like. Then counting from 4b.
