Design of Parallel IN - Serial OUT Shift Register using Behavior Modeling Style (Verilog CODE).

Design of Parallel In - Serial OUT Shift Register using Behavior Modeling Style -

Output Waveform :  Parallel IN - Serial OUT Shift Register

Verilog CODE -

// Title       : parallel_in_serial_out
// Design      : vhdl_upload2
// Author      : Naresh Singh Dobal
// Company     :
// Verilog HDL Programs &  Exercise with Naresh Singh Dobal.
// File        : Parallel IN -  Serial OUT Shift Register.v

module parallel_in_serial_out ( din ,clk ,reset ,load ,dout );

output dout ;
reg dout ;

input [3:0] din ;
wire [3:0] din ;
input clk ;
wire clk ;
input reset ;
wire reset ;
input load ;
wire load ;

reg [3:0]temp;

always @ (posedge (clk)) begin
if (reset)
temp <= 1;
else if (load)
temp <= din;
else begin
dout <= temp[3];
temp <= {temp[2:0],1'b0};

plzz give the testbench code for this...

plzz write the same code to run for 8 times

Pl. correct the code. When reset signal is high then temp variable should be loaded with Zero not one.

would you please explain why temp <= {temp[2:0],1'b0}; line is used.
