HardCopy II devices. Unlike Stratix II devices, where this feature can be
eliminated prior to compiling a final version of the design, HardCopy II
devices are masked programmed and this feature will remain permanent
in the HardCopy II device. Therefore, if the design requires optimal
performance and resource utilization, Altera recommends using this
feature on the Stratix II prototype device, but eliminating it prior to
recompiling the design for a HardCopy II device.
When designing a board with a Stratix II prototype device and its
companion HardCopy II device, most configuration pins required by the
Stratix II device are not required by the HardCopy II device. To maximize
I/O pin counts with HardCopy II device utilization, Altera recommends
minimizing power up and configuration pins that will not carry over
from a Stratix II device into a HardCopy II device.
dedicated and optional configuration pins that a Stratix II device can use
and if their optional functionality is used on a HardCopy II device.
If the HardCopy II device can use the pin’s optional function found in
Stratix II devices, the Quartus II software allows you to set these pins as
dual purpose pins. As dual purpose pins, they have I/O functionality
after power up, reconfiguration and initialization. These pins will only
switch to their I/O designation when the device enters user mode (when
INIT_DONE is asserted). The design may require that some signals be
present when the device transitions into user mode, so you should not
use dual purpose pins because it may result in unstable operation after
power up for both the HardCopy II and the Stratix II devices.
