Example of Performing a Timing Simulation of a Synplify Verilog HDL Design with a Custom Megafunction Variation with the ModelSim Software

To perform a timing simulation on your design using the ModelSim software once you compile your design in the Quartus® Prime software, you can create a script that performs the following steps:
  • Compiles the <device family> _atoms.v library.
  • Compiles the Verilog Output File (.vo) Definitionthe Quartus® Prime software generates during compilation. In this example, the Verilog Output File name is pllsource.vo.
  • Compiles the test bench file. In this example, the test bench file name is plltest.v.

You can simulate the sample design in the ModelSim software by using the commands shown in the following sample script: 

vlib work                                               # Create working directory
vlog /quartus/eda/sim_lib/apex20ke_atoms.v              # Read the simulation library 
                                                        # /quartus/ is the path to 
               Quartus® Prime
vlog pllsource.vo                                       # Compile 
               Quartus® Prime output netlist
vlog plltest.v                                          # Compile test fixture
vsim -t ps work.plltest                                 # Simulate plltest with resolution in ps
add wave /plltest/*                                     # Add the port signals to the waveform view
run 1000 ns                                             # Run the simulation for 1000 ns
