Alternate IEEE libraries supplied

The installation directory may contain two or more versions of the IEEE library:

• ieeepure
  Contains only IEEE approved std_logic_1164 packages (accelerated for ModelSim).
• ieee
  Contains precompiled Synopsys and IEEE arithmetic packages which have been accelerated by Model Technology including math_complex, math_real, numeric_bit, numeric_std, std_logic_1164, std_logic_misc, std_logic_textio, std_logic_arith, std_logic_signed, std_logic_unsigned, vital_primitives, vital_timing, and vital_memory.

You can select which library to use by changing the mapping in the modelsim.ini file. The modelsim.ini file in the installation directory defaults to the ieee library.
