You only need to purchase a license for the FFT MegaCore function when you are
completely satisfied with its functionality and performance, and want to take your
design to production. After you purchase a license, you can request a license file from
the Altera website at www.altera.com/licensing and install it on your computer.
When you request a license file, Altera emails you a license.dat file. If you do not have
Internet access, contact your local Altera representative.

OpenCore Plus Evaluation of
OpenCore Plus hardware evaluation supports the following operation modes:
■
■
All megafunctions in a device time-out simultaneously when the most restrictive
evaluation time is reached. If there is more than one megafunction in a design, a
specific megafunction’s time-out behavior might be masked by the time-out behavior
of the other megafunctions.
The untethered time-out for the FFT MegaCore function is one hour; the tethered
time-out value is indefinite.
The signals source_real, source_imag, and source_exp are forced low when
the evaluation time expires.
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
megafunctions.
Program a device and verify your design in hardware.
Untethered—the design runs for a limited time.
Tethered—requires a connection between your board and the host computer. If
tethered mode is supported by all megafunctions in a design, the device can
operate for a longer time or indefinitely.
