Design Simulation
Simulation allows you to verify design behavior before device programming.Intel® Quartus® Prime software supports RTL- and gate-level design simulation in various third-party simulators.
Simulating a design involves:
- Setting up your simulator working environment
- Compiling simulation model libraries
- Running the simulator
- Interpreting the results
Intel® Quartus® Prime software supports both Verilog
         HDL and VHDL simulation of encrypted and unencrypted Intel FPGA IP cores. 
Note: If your design includes Intel FPGA IP cores, you must compile any
            corresponding IP simulation models in your simulator with the rest of your design and
            testbench. Intel® Quartus® Prime software generates and copies the
            simulation models for IP cores to your project directory.
Note: For more information about using
         EDA simulators, refer to the Intel® Quartus® Prime Pro Edition User
            Guide: Third-party Simulation.
