Hot-Socketing Feature Implementation

Arria II devices are immune to latch-up when using the hot-socketing feature. The
hot-socketing feature turns off the output buffer during power up and power down of
the V
circuitry generates an internal HOTSCKT signal when the V
supplies for Arria II GX devices are below the threshold voltage.

Hot-socketing circuitry is designed to prevent excess I/O leakage during power up.
When the voltage ramps up very slowly, it is still relatively low, even after the POR
signal is released and the configuration is completed. The CONF_DONE, nCEO, and
nSTATUS pins fail to respond, as the output buffer cannot flip from the state set by the
hot-socketing circuit at this low voltage. Therefore, the hot-socketing circuit is
removed on these configuration pins to ensure that they are able to operate during
configuration. Thus, it is the expected behavior for these pins to drive out during
power-up and power-down sequences.
Altera uses GND as reference for hot-socketing operation and I/O buffer designs. To
ensure proper operation, Altera recommends connecting the GND between boards
before connecting to the power supplies. This prevents the GND on your board from
being pulled up inadvertently by a path to power through other components on your
board. A pulled up GND can otherwise cause an out-of-specification I/O voltage or
current condition with the Altera
