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.
Quartus II Software Support
Implementation in your design requires a remote system upgrade interface between
the Cyclone IV device logic array and 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, ALTREMOTE_UPDATE megafunction and 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.
