The user watchdog timer is not enabled during the configuration cycle of the device.
Errors during configuration are detected by the CRC engine. Also, the timer is
disabled for factory configuration. Functional errors must not exist in the factory
configuration because it is stored and validated during production and is never
updated remotely.
The user watchdog timer is disabled in factory configurations and during the
configuration cycle of the application configuration. It is enabled after the application
configuration enters user mode.
Implementation in your design requires a remote system upgrade interface between
the Cyclone III device family logic array and the remote system upgrade circuitry. You
must also generate configuration files for production and remote programming of the
system configuration memory. The Quartus II software provides these features.
The two implementation options, the ALTREMOTE_UPDATE megafunction and the
remote system upgrade atom, are for the interface between the remote system
upgrade circuitry and the device logic array interface. Using the megafunction block
instead of creating your own logic saves design time and offers more efficient logic
synthesis and device implementation.
For more information about the ALTREMOTE_UPDATE megafunction, refer to the
Remote Update Circuitry (ALTREMOTE_UPDATE) Megafunction User
