Installation and Licensing

January 2014 Altera Corporation Asynchronous Serial Interface (ASI) MegaCore Function User Guide

■ 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.

f For more information on OpenCore Plus hardware evaluation using the ASI, refer to

AN 320: OpenCore Plus Evaluation of Megafunctions.

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.

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 and the

rst

signal goes high.
