Description
Due to a bug in the Quartus® II software version 14.0 and earlier xcvr_diffmifgen.exe tool, the reduced MIF file is missing some RX PMA settings for Arria® V, Cyclone® V, and Stratix® V devices.
Resolution
To work around this problem you can use the full transceiver MIF file.
This problem is fixed in the Quartus II software version 14.1.
