Quartus II software provides the flexibility to include the remote system
upgrade interface between the Stratix III device logic array and the
dedicated circuitry, generate configuration files for productions, and
remote programming of the system configuration memory.
The implementation option altremote_update megafunction in
Quartus II is 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.
altremote_update Megafunction
The altremote_update megafunction provides a memory-like interface to
the remote system upgrade circuitry and handles the shift register
read/write protocol in Stratix III 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.
