Code

/*Write your code here*/
module bin2gray4 (
    input [3:0] bin_in,
    output reg [3:0] gray_out
);
    always @(bin_in) begin
    case(bin_in)
        4'b0000 : gray_out <= 4'b0000;
        4'b0001 : gray_out <= 4'b0001;
        4'b0010 : gray_out <= 4'b0011;
        4'b0011 : gray_out <= 4'b0010;
        4'b0100 : gray_out <= 4'b0110;
        4'b0101 : gray_out <= 4'b0111;
        4'b0110 : gray_out <= 4'b0101;
        4'b0111 : gray_out <= 4'b0100;
