My code:

`timescale 10ns/100ps
module Verilog1;
wire [7:0]out;
reg [2:0]pin;
lab_1 g1(pin,out);
initial
begin
pin[1]=1'b0; pin[2]=1'b0; pin[3]=1'b0;
#3 pin[1]=1'b0; pin[2]=1'b0; pin[3]=1'b1;
#3 pin[1]=1'b0; pin[2]=1'b1; pin[3]=1'b0;
#3 pin[1]=1'b1; pin[2]=1'b0; pin[3]=1'b0;
#3 pin[1]=1'b0; pin[2]=1'b1; pin[3]=1'b1;
#3 pin[1]=1'b1; pin[2]=1'b1; pin[3]=1'b0;
#3 pin[1]=1'b1; pin[2]=1'b0; pin[3]=1'b1;
#3 pin[1]=1'b1; pin[2]=1'b1; pin[3]=1'b1;
end
initial
#50 $stop;
endmodule
