Critical Issue
Description
Not all variants of the SerialLite III Streaming IP core support maximum lanes. This is due to timing closure challenges. The following table lists the SerialLite III Streaming IP Core Stratix V variants that can close timing at 10% margin with respect to the number of lanes. Other variants not listed in the table will face timing closure challenges.
Resolution
Use high fitting effort to increase the number of lanes that the core can support.
