It's recommended to use the ieee.numeric_std library on new designs. There are many convenient conversion functions in that library, including to_unsigned which will convert a natural integer and a std_logic_vector to unsigned. 2. For older designs that use the ieee.std_logic_arith library there's no need to change anything.
