Most optional configuration pins listed in
configuration schemes available in Stratix II FPGAs. Parallel
programming and remote update configuration modes utilize most of the
pins in
support the Configuration Emulation mode. Therefore, Altera
recommends that you minimize the configuration pin requirements of the
Stratix II design; for example, by using the Passive Serial configuration
mode.
If some of these dual-purpose pins are needed to configure the Stratix II
FPGA, but will be unused after configuration, these pins will be
completely unused on the HardCopy II device. Therefore, when
migrating from the Stratix II device to the HardCopy II device, care must
be taken when designing these pins on board. The removal of the
Stratix II device and its corresponding configuration device may leave
these pins floating on the HardCopy II device if such pins are assigned as
inputs by the user, without any external means of driving them to a stable
level. When selecting a Stratix II device and its device options, consider
the after-configuration requirements of these pins and set them
appropriately in the Quartus II software
