Configuration Schemes
You can load the configuration data for a Stratix II GX device with one of
five configuration schemes (refer to Table 3–4), chosen on the basis of the
target application. You can use a configuration device, intelligent
controller, or the JTAG port to configure a Stratix II GX device. A
configuration device can automatically configure a Stratix II GX device at
system power-up.
Multiple Stratix II GX devices can be configured in any of the five
configuration schemes by connecting the configuration enable (nCE) and
configuration enable output (nCEO) pins on each device. Stratix II GX
FPGAs offer the following:
■ Configuration data decompression to reduce configuration file
storage
■ Design security using configuration data encryption to protect
designs
■ Remote system upgrades for remotely updating Stratix II GX designs
Table 3–4 summarizes which configuration features can be used in each
configuration scheme.
Refer to the Configuring Stratix II & Stratix II GX Devices chapter in
volume 2 of the Stratix II GX Device Handbook for more information about
configuration schemes in Stratix II GX devices.
