59. Absolute Value

Use an inline if condition to evaluate and convert to absolute value

module abs8_func (
    input  signed [7:0] a,
    output       [7:0] abs
);
    // ---------- Write function here----------
    function [7:0] abs8;
    input signed [7:0] x;
    begin
        abs8 = (x>=0)?x:-x;
    end
    endfunction

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

endmodule
