28. Divide-by-4 Tick Generator

How do you plan to solve it?

module tick_div4(
  input  wire clk,
  input  wire rst,
  output reg  tick
);
  reg [1:0] cnt;

  always @(posedge clk) begin
    if (rst == 1'b1) begin
      cnt  <= 2'b00;
      tick <= 1'b0;
    end else begin
      if (cnt == 2'b11) begin
        cnt  <= 2'b00;
        tick <= ~tick;     // toggle every 4 clock cycles
      end else begin
              tick <= 1'b0;

        cnt  <= cnt + 1'b1;
      end
    end
  end
