DDR3 Recovery Failures on Stratix V Devices

Description

This problem affects DDR3 products.

DDR3 interfaces on Stratix V devices may fail recovery analysis in the example design for transfers within the traffic generator. Such failures affect only quarter-rate designs and occur only inside the traffic generator. You can ignore these failures because they happen on transfers that do not require 1T timing.

Workaround/Fix

The workaround for this issue is to set the affected paths as false paths in the user-defined SDC files.

This issue will be fixed in a future version.
