11. Vector Concatenation

How do you plan to solve it?

/*Write your code here*/
module concat8_packer(A, B , C, D, OUT);
    input [3:0]A;
    input [1:0]B;
    input C, D;
    output [7:0] OUT;

    assign OUT[7:4] = A;
    assign OUT[3:2] = B;
    assign OUT[1] = ~C;
    assign OUT[0] = D;
endmodule
