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]in;
        // output [7:0] out;
        begin 
            abs8=(in<0) ? -in: in;
        end
    endfunction


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