OpenCore Plus Evaluation

With Altera’s free OpenCore Plus evaluation feature, you can perform

the following actions:

■ Simulate the behavior of a megafunction (Altera MegaCore function

or AMPP

megafunction) within your system

■ Verify the functionality of your design, as well as evaluate its size

and speed quickly and easily

■ Generate time-limited device programming files for designs that

include MegaCore functions

■ Program a device and verify your design in hardware

You only need to obtain a license for the megafunction when you are

completely satisfied with its functionality and performance, and want to

take your design to production.

f For more information on OpenCore Plus hardware evaluation using the

RLDRAM II controller, refer to “OpenCore Plus Time-Out Behavior” on

page 2–12 and AN 320: OpenCore Plus Evaluation of Megafunctions.
