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 timeout is 1 hour; the tethered timeout value
is indefinite.
Your design stops working after the hardware evaluation time expires, and the
following events occur:
■
■
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
