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 purchase a license for the megafunction when you are completely
satisfied with its functionality and performance, and want to take your design to
production.
