Oct 19, 2015 · Verilog Code for 4 bit Ring Counter with Testbench A ring counter is a digital circuit with a series of flip flops connected together in a feedback manner.The circuit is special type of shift register where the output of the last flipflop is fed back to the input of first flipflop.When the circuit is reset, except one of the flipflop output,all others are made zero.
Verilog Ring Counter. A ring counter is a digital circuit with a series of flip flops connected in a feedback manner. Ring Counter is composed of Shift Registers. The data pattern will re-circulate as long as clock pulses are applied. The circuit is a special type of shift register where the last flip flop's output is fed back to the input of ...
May 6, 2023 · Here’s an example Verilog code to implement a 4-bit ring counter circuit: module ring_counter (output reg [3:0] count, input clk); always @(posedge clk) begin count = {count[2:0], count[3]}; end endmodule This code defines a module called "ring_counter" that implements a 4-bit ring counter. The output "count" is a registered output that represents the current state of the counter. The input "clk" is the clock input that controls the counter operation.
Feb 17, 2015 · I have the task of designing a ring counter in verilog using shift operator. Here is the code so far along with test bench : module ring ( input wire [3:0] data, input wire clk, input wire rst, input wire load, output reg [3:0] q ) ; /*When the load pin is High, the data is loaded in the counter on clock transition.
It then becomes 0010 at the next clock cycle - and this keeps going on. 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. a = 4'b0001; a <= a <<1; // Notice the blocking assignment.

Jan 19, 2023 · Twisted Ring Counter – It is also known as a switch-tail ring counter, walking ring counter, or Johnson counter. It connects the complement of the output of the last shift register to the input of the first register and circulates a stream of ones followed by zeros around the ring. Here, we use Clock (CLK) for all the flip-flops.
A Ring Counter is a type of Digital Counter that consists of a series of flip-flops connected in a circular fashion. A ring counter using 4 D Flip-Flops can be constructed by connecting the Q output of each DFF to the D input of the next DFF in a circular fashion, and connecting the output of the last DFF back to the input of the first DFF.
Ring Counters. PDF Version. If the output of a shift register is fed back to the input. a ring counter results. The data pattern contained within the shift register will recirculate as long as clock pulses are applied. For example, the data pattern will repeat every four clock pulses in the figure below. However, we must load a data pattern.
