8–80 Chapter 8: Configuration and Remote System Upgrades in Cyclone IV Devices Document Revision History 1 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. f For more information about the ALTREMOTE_UPDATE megafunction, refer to the Remote Update Circuitry (ALTREMOTE_UPDATE) Megafunction User Guide.
