module abs8_func (
    input  signed [7:0] a,
    output   wire [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);
