Remote System Upgrades
Stratix V Device Handbook Volume 2: Device Interfaces and Integration

This section describes the functionality and implementation of the dedicated remote
system upgrade circuitry. It also defines several concepts related to remote system
upgrades, including factory configuration, application configuration, remote update
mode, and user watchdog timer. Additionally, this section provides design guidelines
for implementing remote system upgrades with the supported configuration
schemes.
System designers sometimes face challenges such as shortened design cycles,
evolving standards, and system deployments in remote locations. Stratix V devices
help overcome these challenges with their inherent reprogrammability and dedicated
circuitry to perform remote system upgrades. Remote system upgrades help deliver
feature enhancements and bug fixes without costly recalls, reduce time-to-market,
extend product life, and help to avoid system downtime.
Stratix V devices feature dedicated remote system upgrade circuitry. A soft logic
(either the Nios
device can download a new configuration image from a remote location, store it in
configuration memory, and direct the dedicated remote system upgrade circuitry to
start a reconfiguration cycle. The dedicated circuitry performs error detection during
and after the configuration process, recovers from any error condition by reverting
back to a safe configuration image, and provides error status information.
Remote system upgrades are supported in AS configuration schemes with EPCS and
EPCQ devices. You can also implement remote system upgrades in conjunction with
advanced Stratix V features such as real-time decompression of configuration data
and design security using the advanced design security standard (AES) for secure and
efficient field upgrades. The largest EPCS and EPCQ device currently supports
128 Mbits and 256 Mbits configuration data respectively.
Remote system upgrades are supported only in single-device configurations.
The remote system upgrade process in Stratix V devices involves the following steps:
1. A Nios II processor (or user logic) implemented in the Stratix V device logic array
2. The Nios II processor (or user logic) stores this new configuration data in
3. The Nios II processor (or user logic) starts a reconfiguration cycle with the new or
4. The dedicated remote system upgrade circuitry detects and recovers from any

remote source uses a communication protocol such as TCP/IP, PCI, user datagram
protocol (UDP), UART, or a proprietary interface.
