Errata Sheet for Arria II GX Devices
Error Detection CRC Feature
When enabled, the Error Detection CRC feature may cause the
MLAB RAM blocks to operate incorrectly.
M9K RAM Block Lock-Up
The M9K RAM blocks may lock up due to a glitchy non-PLL
clock.
Automatic Clock Switchover
The automatic clock switchover feature may not operate correctly.
Remote System Upgrade
The remote system upgrade feature fails when loading an invalid
configuration image.

The transmitter phase-locked loop (PLL) lock status signal (pll_locked) does not
de-assert when the pll_powerdown signal is asserted in configurations that use the
reference clock pre-divider of 2, 4, or 8.
inside transmitter PLLs. This issue impacts the pll_locked status signal in the clock
multiplier unit (CMU) PLL.
Designs that implement the recommended transceiver reset sequence described in the
Reset Control and Power Down in Arria II Devices
Device Handbook could potentially see a link failure after coming out of reset.
