9. XOR Gate Using Basic Gates

How do you plan to solve it?

// ============================================================
// Basic Gates (given)
// ============================================================
module and_gate(input a, b, output y);
    assign y = a & b;
endmodule

module or_gate(input a, b, output y);
    assign y = a | b;

endmodule

module not_gate(input a, output y);
    assign y = !a;

endmodule

// ============================================================
// XOR Gate
// ============================================================
module xor_gate (
    input  a, b,
    output y
);
    wire b_not, a_not;
    wire a_bnot, anot_b;

    

    not_gate not_a (.a(a), .y(a_not));
    not_gate not_b (.a(b), .y(b_not));

    and_gate and1 (.a(a), .b(b_not), .y(a_bnot));
    and_gate and2 (.b(b), .a(a_not), .y(anot_b));
     
    or_gate final (.a(a_bnot), .b(anot_b), .y(y));


endmodule
