About Using the ModelSim Software with the Quartus II Software
You can perform a functional and/or a timing simulation of a Quartus II–generated design with the Mentor Graphics ModelSim-Altera software that was provided with the Quartus II software, or the ModelSim PE or SE software from Mentor Graphics . The ModelSim software is a dual-language simulator; you can simulate designs containing either Verilog HDL, VHDL, or both. You can use designs in which a Verilog HDL module instantiates VHDL entities or a VHDL module instantiates Verilog HDL entities.
ModelSim-Altera Design Flow
The following topics describe the typical functional and timing simulation flow with the ModelSim-Altera (OEM) software:
