Preliminary
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 timeout is one hour; the tethered timeout
value is indefinite.
Your HyperTransport MegaCore function variation is forced into a cold reset state
when the hardware evaluation time expires.
