Aren't integers limited to 32-bit values in VHDL? I think the standard just says "at least" 32 bits but I don't know what Quartus actually uses.

Anyway I'm not sure it is safe to use something like 16#55555555555555#. I think it's better to stick to vectors (including the signed and unsigned types) when dealing with values that need more than 32 bits.
