■
Generate time-limited device programming files for designs that include
megafunctions
■
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.

OpenCore Plus Time-Out Behavior
OpenCore Plus hardware evaluation can support the following two modes of
operation:
■
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.

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 and the rst
signal goes high.
