How do you plan to solve it?

 

 

Code

module tick_div4(
  input  wire clk,
  input  wire rst,
  output reg  tick
);
  reg [1:0] cnt;
  always @(posedge clk) begin
    // Write your code here

    if(rst) begin

      cnt <= 2'b0;
      tick <= 1'b0;

    end

    else begin

      if(cnt == 3) begin

        tick <= 1'b1;
        cnt  <= 2'b0;

      end

    


    else begin

      cnt <= cnt + 1;
      tick <= 1'b0;


    end


    end
      


    
  end
