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 megafunctions.
■
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.
After you purchase a license for PCI Compiler MegaCore function, you
can request a license file from the Altera website at
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 Time-Out Behavior
OpenCore Plus hardware evaluation supports the following two
operation modes:
■
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.
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
may be masked by the time-out behavior of the other megafunctions.
1
For MegaCore functions, the untethered time-out is 1 hour; the
tethered time-out value is indefinite.
Your design stops working after the hardware evaluation time expires.
