OpenCore Plus Time-Out Behavior
OpenCore
Plus hardware evaluation supports the following 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 might be masked by the time-out behavior
of the other megafunctions.
The untethered timeout for the FIR Compiler MegaCore function is one hour; the
tethered timeout value is indefinite.
The data output signal is forced to zero when the hardware evaluation time expires.
