BINARY TO GRAY CONVERTER

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

module bin_to_gray(

input clk,

input [2:0]binary,

output reg[2:0]gray

);

always@(posedge clk)

begin

gray[2] = binary[2];

gray[1] = binary[2] ^ binary[1];

gray[0] = binary[1] ^ binary[0];

end

endmodule
