How do you plan to solve it?
in the fan out we have to connect the input to the different number of output ports so i just assign to the y1,y2,y3 the input a.
module top_module( // Declare Inputs and outputs here input a, output y1, output y2, output y3 ); // Module functionality here assign y1 = a; assign y2 = a; assign y3 = a; endmodule
