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 SM
megafunction) within your system.
■ Verify the functionality of your design and quickly evaluate its size and speed
with ease.
■ Generate time-limited device programming files for designs that include
MegaCore functions.
■ Program a device and verify your design in hardware.
You are required to obtain a license for the MegaCore function only when you are
completely satisfied with its functionality and performance, and want to take your
design to production.
