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] a;

    begin
        

        if(a<0) begin

            abs8 = -1*a;

        end

        else begin

            abs8 = a;

        end
        
    end

endfunction 



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