In XAUI functional mode, the data out of the channel 0 Rate Match FIFO may be
shifted by one byte with respect to the data of the other three channels. This causes
incorrect idle ordered set conversion, resulting in incorrect received parallel data. This
issue happens only during initialization or receiver channel reset (assertion of
rx_analogreset or rx_digitalreset).
Figure 4
A soft IP solution for this issue is available by contacting Altera.
The Error Detection CRC feature is typically used to detect single event upsets (SEU).
When enabled, the Error Detection CRC feature may cause the memory logic array
block (MLAB) RAM to operate incorrectly in Arria II GX ES devices. Only write
operations in the MLAB RAM blocks are affected.
The Error Detection CRC feature and CRC error flag operate correctly. FPGA
configuration bits are not affected by this issue.
If you do not use Error Detection CRC, no action is required. The MLAB RAM blocks
will operate correctly.
If you enable Error Detection CRC, disabling the Error Detection CRC resolves the
problem.
Also, using M9K RAM blocks or Logic Cells (LCs) instead of MLAB RAM blocks
resolves the problem.
This issue will be fixed in production devices.
