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
    // Write your code here
    if(rst)
    begin
      pulse <= 0;
      prev <= 0;
    end
    else
    begin
      pulse <= ((~prev) & sig_in);
      prev <= sig_in;
    end
  end
