OpenCore Evaluation of
AMPP Megafunctions
February 2004, ver 1.0 Application Note 343
Introduction The Altera Megafunction Partner Program (AMPPSM) is a community of
independent companies that offer reusable intellectual property for
Altera® devices. These intellectual property products, also known as
megafunctions, offer a broad range of solutions for a diverse set of FPGA
applications. Using megafunctions in your design saves time spent in
both design and verification, while maintaining a high standard of
quality.
With Altera’s free OpenCore evaluation feature, you can perform the
following actions:
■ Simulate the behavior of a megafunction within your system
■ Verify the functionality of your design, as well as evaluate its size
and speed quickly and easily
1 Altera's OpenCore feature does not support programming file
generation and/or hardware evaluation. For information about
these and other features of OpenCore Plus evaluation, refer to
AN 320: OpenCore Plus Evaluation of Megafunctions.
This document describes how to instantiate an AMPP function into a
design and evaluate it using the OpenCore feature.
Obtaining and To request an AMPP megafunction that supports OpenCore evaluation
directly from the Altera web site, perform the following steps:

2. Use the search engine to generate a table of megafunctions that fit
your search criteria.
3. Click the name of the megafunction you wish to evaluate. The
product description web page displays, listing the name of the
AMPP partner who is offering the megafunction, and an overview
of the megafunction’s features.
4. Click Request Free Evaluation and follow the instructions for
submitting a request.

When you submit a request, an e-mail message containing your contact
and project information is sent to the AMPP megafunction partner. The
partner will respond to your request with an OpenCore version of the
megafunction and an evaluation license file.
1 Make sure to populate the web request with complete and
accurate information. Failure to do so may jeopardize the receipt
of an OpenCore megafunction.
1 Delivery methods for OpenCore evaluations may vary slightly
for each AMPP partner. Make sure to follow the instructions
provided by the AMPP partner.
The license file contains an Altera FEATURE line that enables compilation
and simulation of the megafunction in Altera's Quartus® II software
(Figure 1).
Figure 1. AMPP Megafunction License FEATURE Line
To license an AMPP megafunction for OpenCore evaluation, perform the
following steps:
1. Open the megafunction license file in a text editor. The file should
contain one FEATURE line spanning two or more lines in the file.
2. Open your Quartus II license.dat file in a text editor.
3. Copy the FEATURE line from the megafunction license file and paste
it at the end of your Quartus II license file.
4. Start the Quartus II software and choose License Setup (Tools
menu).
5. Confirm that the path to your Quartus II license file appears in the
License File dialog box (Figure 2).

6. Confirm that the appropriate vendor (AMPP partner) name and
product ID appear in the "Licensed AMPP/MegaCore functions"
box (Figure 2).
You are now ready to evaluate your AMPP megafunction.

Each AMPP partner provides instructions on how to install their product
into the Altera design environment. It is important to follow the
directions carefully, since many products require multiple installation
steps.
Parameterize, Instantiate, and Compile
Some AMPP megafunctions are designed with a set of user-selectable
parameters. The OpenCore design flow allows you to evaluate the impact
of different parameter settings on the overall design. These options
should be set prior to compilation in the Quartus II software. Refer to the
documentation included by the AMPP partner on how to instantiate the
megafunction and set any applicable parameters.
Once you have properly instantiated the megafunction into your design,
compile the Quartus II project and evaluate resource utilization and static
timing analysis results.

Conclusion
f Refer to the Introduction to Quartus II Manual for information on
compiling your design using the Quartus II software.
Simulate
After successful compilation, you can simulate using the Quartus II
software. You can perform the compilation and simulation steps as many
times as required.
1 Some AMPP vendors also support simulation platforms outside
the Quartus II software. Contact the AMPP partner for details.
f Refer to the Introduction to Quartus II Manual for information on
simulating your design using the Quartus II software.
Purchase
When the you are satisfied with the results of the megafunction
evaluation, you can purchase a license for the megafunction. All
negotiation involving licensing, purchase, and deliverables takes place
exclusively between you and the AMPP partner.
Conclusion The OpenCore feature allows you to evaluate AMPP megafunctions risk-
free. You can use the OpenCore feature to instantiate, compile, and
simulate an AMPP megafunction before deciding to purchase the
megafunction from the AMPP partner.
