Arria II GX device I/O pins are hot-socketing compliant without the need for external
components or special design requirements. Hot-socketing support in Arria II GX
devices has the following advantages:
■
■
■
You can drive signals into regular and transceiver Arria II GX I/O pins before or
during power up or power down without damaging the device. Arria II GX devices
also support power up or power down of the power supplies in any sequence to
simplify the system-level design.
A device that does not support hot socketing may interrupt system operation or cause
contention by driving out before or during power up. In a hot-socketing situation, the
Arria II GX device output buffers are turned off during system power up or power
down. Also, the Arria II GX device does not drive out until the device is configured
and working within recommended operating conditions.
Devices that do not support hot socketing can short power supplies when
powered up through the device signal pins. This irregular power up can damage both
the driving and driven devices and can disrupt card power up.
An Arria II GX device may be inserted into (or removed from) a powered up system
board without damaging or interfering with system-board operation.
You can power up or power down the V
and at any time between them. The power supply ramp rates can range from 50 s to
100 ms.

I/O pins remain tri-stated during power up. The device does not drive out before
or during power up, thereby not affecting other buses in operation.
