2-Input XOR Function Example - 2023.2 English

In this coding example, each instance of the built-in modules has a unique instantiation name such as a_inv, b_inv, and out.

module build_xor (a, b, c);
input a, b;
output c;
wire c, a_not, b_not;

not a_inv (a_not, a);not b_inv (b_not, b);and a1 (x, a_not, b);and a2 (y, b_not, a);or out (c, x, y);
endmodule
