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, 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.
