sixteen bits adder

[light]

hi
can someone help me?


module full_adder(s,cout,a,b,cin);
input a,b,cin;
output s,cout;

assign s=(a^b)^cin
assign cout=((a^b)&cin)|(a&b);

endmodule

input [15:0] A,B;

Make it ready and send it back, it doesn't seem to be a question. Stackoverflow would be beneficial for you.
