How do you plan to solve it?

 

 

Code

// ============================================================
// 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
);
assign y= (~a&b)|(~b&a);

endmodule
