Bus invert

Design a circuit that transfers or inverts the value of an $N$ -bit bus. A control signal called invert will determine whether the value must be transferred (invert=0) or inverted (invert=1). $N$ must be a parameter of the circuit with default value 8.

Specification

module bus_transfer_invert(in, invert, out);
    parameter N=8;
    input [N-1:0] in;
    input invert;
    output [N-1:0] out;

Input

in is the $N$ -bit input bus.
invert is the control signal that determines whether the value of the bus must be transferred or inverted.

Output

out is the $N$ -bit inverted value of the bus.
