GRAY TO BINARY CONVERTER

This program is to convert gray code to binary code. The logic behind conversion is the most significant bit is same and the consequent bits are the result of ex-or of gray and binary bits. 

  

module bin_to_gray(

input clk,

input [2:0]gray_input,

output reg [2:0]bin_out

);

always@(posedge clk)

begin

bin_out[2] <= gray_input[2];

bin_out[1] <= bin_out[2] ^ gray_input[1];

bin_out[0] <= bin_out[1] ^ gray_input[0];

end

endmodule
