Hi,

I think it is working fine just confirm below things,

  1. have you provided 2`s complement input stimulus for negative input?
  2. provide 'add' input stimulus & confirm the 'i' value since in logic it depends & decide the addition /subtraction , ensure it from simulation window.

i(0) <= '0' when am >= bm else '1';

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

Best Regards
