2. Fan-Out Wire

How do you plan to solve it?

module top_module(
    // Declare Inputs and outputs here
    input a,
    output y1,y2,y3
);
    // Module functionality here
    wire w1,w2,w3;
    assign w1 = a;
    assign w2 = a;
    assign w3 = a;
    assign y1 = w1;
    assign y2 = w2;
    assign y3 = w3;

endmodule
