Figure 12–12. Remote System Configuration Using Enhanced Configuration Devices
Altera Corporation
September 2004
Remote Source
Configuration Data
Application
(Network)
The user watchdog timer in Stratix and Stratix GX devices ensures that an
application configuration has loaded successfully and checks if the
application configuration is operating correctly in user mode. The
watchdog timer must be continually reset by the user logic. If an error
occurs while the application configuration loads, or if the watchdog timer
times-out during user mode, the factory configuration is reloaded to
prevent the system from halting in an erroneous state.
page 12–4
Upon power-up in local configuration scheme, the application
configuration at page 001 (PGM[001] of the enhanced configuration
device) loads into the Stratix or Stratix GX device. This application can be
remotely or locally updated. If an error occurs during loading of the
configuration data, the factory configuration loads automatically (see
Figure 12–4 on page
mode.
Local Update Programming File Generation
This section describes the programming file generation process for
performing remote system upgrades. The Quartus II convert
programming files (CPF) utility generates the initial and partial
programming files for configuration memory within the enhanced
configuration devices.
The two pages that local configuration mode uses are a factory
configuration stored at page 000, and an application configuration stored
at page 001. The factory configuration cannot be updated after initial
production programming. However, the application configuration can be
erased and reprogrammed after initial system deployment.
