Simulating in MATLAB
To simulate in a MATLAB environment, run the <variation_name>_model.m testbench
m-script, which also is located in your design directory. This script also uses the file
<
variation name>_input.txt to provide input data. The output from the MATLAB
simulation is stored in the file <variation name>_model_output.txt.
For MCV decimation filters, the <variation name>_model_output_full.txt file is
generated to display all the phases of the filter. You can compare this file with the
<
variation name>_output.txt file to understand which phase the output belongs. For
all other architectures, decimation filters provide the Nth phase where N is the
decimation factor.
Simulating in Third-Party Simulation Tools Using NativeLink
You can perform a simulation in a third-party simulation tool from within the
Quartus II software, using NativeLink.
The Tcl script file <variation name>_nativelink.tcl can be used to assign default
NativeLink testbench settings to the Quartus II project.
To perform a simulation in the Quartus II software using NativeLink, perform the
following steps:
1. Create a custom MegaCore function variation as described earlier in this chapter
but ensure you specify your variation name to match the Quartus II project name.
2. Verify that the absolute path to your third-party EDA tool is set in the Options
page under the Tools menu in the Quartus II software.
3. On the Processing menu, point to Start and click Start Analysis & Elaboration.
4. On the Tools menu, click Tcl scripts. In the Tcl Scripts dialog box, select
< variation name>_nativelink.tcl and click Run. Check for a message confirming
that the Tcl script was successfully loaded.
5. On the Assignments menu, click Settings, expand EDA Tool Settings, and select
Simulation . Select a simulator under Tool name then in NativeLink Settings,
select Compile test bench and click Test Benches.
6. On the Tools menu, point to EDA Simulation Tool and click Run EDA RTL
Simulation .
The Quartus II software selects the simulator, and compiles the Altera libraries,
design files, and testbenches. The testbench runs and the waveform window
shows the design signals for analysis.

Quartus II Handbook.
Compile the Design and Program a Device
You can use the Quartus II software to compile your design.
After you have compiled your design, program your targeted Altera device and
verify your design in hardware.
