Theory :

The XOR (Exclusive-OR) gate is a digital logic gate that outputs HIGH (1) only when the number of HIGH inputs is odd.

1. For a 2-input XOR gate, the output is HIGH (1) when the inputs are different.

2. The output is LOW (0) when the inputs are the same

 BLOCK DIAGRAM:

Boolean expression :Y=A⊕B=AB+AB 

Verilog Code :

module XOR(Y,A,B);

input A,B;

output Y;

assign Y = (A^B);

endmodule

Test bench :

module tb_XOR();

reg A,B;

wire Y;

XOR DUX(Y,A,B);

initial 

begin 

    A=1'b0 ; B=1'b0;

    #10 A=1'b0 ; B=1'b1;

    #10 A=1'b1 ; B=1'b0;

    #10 A=1'b1 ; B=1'b1;

    #20 $finish();

    end 

endmodule

OUTPUT :

 Pin Assignment: 

Input A = J15

Input B = L16

Output Y = H17
