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 nota, notb;
    wire w1,w2;
    
   

// NOT Operations
    not_gate u1 (.a(a),.y(nota));
    not_gate u2 (.a(b),.y(notb));

    //AND Operation
and_gate u3 (.a(a), .b(notb), .y(w1));
and_gate u4 (.a(nota), .b(b), .y(w2));
 
    // OR Operation
    or_gate u5 (.a(w1), .b(w2), .y(y));

endmodule
