in fact i checked before with power of 2, but i saw Micheel doing this, 
i thought i
should also do this

--pragma synthesis_off
begin
   assert (WIDTH >= 64) and (WIDTH mod 64 = 0)
       report "width of IAdd must be an integer multiple of 64"
       severity failure;
--pragma synthesis_on

it's more probable that Gaetan didn't make it in a good way...
