Critical Issue
Description
This problem affects QDR II products.
QDR II/II interfaces targeting Arria V devices do not fully support the RTL-based sequencer. If you select the RTL-based sequencer, the resulting IP generates and simulates properly, but calibration in hardware is unreliable.
Resolution
The workaround for this issue is to use the Nios II-based sequencer.
This issue will be fixed in a future version.
