Why do I see the read data corruption with the Stratix® 10 FPGA QDRII+ IP when the calibration passes consistently?

Description

You might observe the read data corruption when there is a large difference in the calibrated DQS-en setting between calibration attempts with the Stratix® 10 FPGA QDRII+ intellectual property (IP).
