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.
The Quartus II software provides the flexibility to include the remote system upgrade
interface between the Arria II device logic array and the dedicated circuitry, generates
configuration files for production, and allows remote programming of the system
configuration memory.
Use the ALTREMOTE_UPDATE megafunction option in the Quartus II software as
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.
The ALTREMOTE_UPDATE megafunction provides a memory-like interface to the
remote system upgrade circuitry and handles the shift register read and write
protocol in the Arria II device logic. This implementation is suitable for designs that
implement the factory configuration functions using a Nios II processor or user logic
in the device.
