Potential Data Corruption on SerialLite III Streaming IP Core Arria 10 Source and Duplex Interface for Lane Rate > 15 Gbps

Description

The SerialLite III Streaming IP core Arria 10 variants for lane rate > 15 Gbps (which uses 64-bit PCS interface) may result in FIFO overrun/underrun condition in the hardened PCS. This is metaframe-specific. When this condition happens, a realignment takes place on the source (Tx) interface and this results in a data corruption on the sink (Rx) interface.

This issue is found in Quartus II versions 14.0, 14.1, and 15.0.

Resolution

Use the metaframe values that are tested below :

For ECC disabled mode, use metaframe = 200, 400, 4000

For ECC enabled mode, use metaframe = 400
