Stratix GX FPGA Family
Multiple Stratix GX devices can be configured in any of five configuration
schemes by connecting the configuration enable (nCE) and configuration
enable output (nCEO) pins on each device.

Partial Reconfiguration
The enhanced PLLs within the Stratix GX device family support partial
reconfiguration of their multiply, divide, and time delay settings without
reconfiguring the entire device. Designers can use either serial data from
the logic array or regular I/O pins to program the PLL’s counter settings
in a serial chain. This option provides considerable flexibility for
frequency synthesis, allowing real-time variation of the PLL frequency
and delay. The rest of the device is functional while reconfiguring the
PLL. See “Enhanced PLLs” on page 143 for more information on
Stratix GX PLLs.
Remote Update Configuration Modes
Stratix GX devices also support remote configuration using an Altera
enhanced configuration device (for example, EPC16, EPC8, and EPC4
devices) with page mode selection. Factory configuration data is stored in
the default page of the configuration device. This is the default
configuration which contains the design required to control remote
updates and handle or recover from errors. The designer writes the
factory configuration once into the flash memory or configuration device.
Remote update data can update any of the remaining pages of the
configuration device. If there is an error or corruption in a remote update
configuration, the configuration device reverts back to the factory
configuration information.
