59. Absolute Value

How do you plan to solve it?

module abs8_func (
    input  signed [7:0] a,
    output       [7:0] abs
);
    // ---------- Write function here----------
    function [7:0]abs8;
        input signed [7:0]x;
        if(x[7] == 1'b1) begin
            abs8 = ~x;
            abs8 = abs8 + 1'b1;
        end
        else begin
            abs8 = x;
        end
        // abs8 = (x < 0) ? -x : x;
    endfunction



    // Function called here
    assign abs = abs8(a);
