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.

Power Up and

Configuration

Compatibility

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. Table 8–21 lists the

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.
