Configuring Stratix II and Stratix II GX Devices
Stratix II and Stratix II GX devices offer design security, decompression,
and remote system upgrade features. Design security using configuration
bitstream encryption is available in Stratix II and Stratix II GX devices,
which protects your designs. Stratix II and Stratix II GX devices can
receive a compressed configuration bit stream and decompress this data
in real-time, reducing storage requirements and configuration time. You
can make real-time system upgrades from remote locations of your
Stratix II and Stratix II GX designs with the remote system upgrade
feature.
for Stratix II and Stratix II GX devices, respectively.

These schemes require that you drive the RUnLU pin to specify either remote update or local update. For more

information.
(3)
These modes are only supported when using a MAX II device or a microprocessor with flash memory for
configuration. In these modes, the host system must output a DCLK that is 4× the data rate.
(4)
Do not leave the MSEL pins floating. Connect them to
VCCPD or ground. These pins support the non-JTAG
configuration scheme used in production. If only JTAG configuration is used, you should connect the MSEL pins to
ground.
(5)
JTAG-based configuration takes precedence over other configuration schemes, which means MSEL pin settings are
ignored.
