Simulation Library
To perform functional and timing simulations, you must use the altera_mf.v library located in the <Quartus® Prime installation directory>\eda\sim_lib directory.
For VHDL, you must use the altera_mf.vhd library located in the <Quartus® Prime installation directory>\eda\sim_lib directory.
The VHDL component declaration file is located in the altera_mf_components.vhd library in the <Quartus II installation directory>\eda\sim_lib directory.
