29. One Shot Pulse

How do you plan to solve it?

module rise_pulse(
  input  wire clk,
  input  wire rst,      // synchronous active-high reset
  input  wire sig_in,
  output reg  pulse
);
  reg prev;             // previous sampled value of sig_in

  always @(posedge clk) begin
    if(rst) begin 
      pulse <= 0;
      prev <=0;
    end else begin
      pulse<=sig_in && !prev;
      prev<=sig_in;
    end
  end
