Version Found: v1.5
Version Resolved and other Known Issues: See (Xilinx Answer 45195).
All MIG 7 series DDR3 RDIMM designs will fail in hardware during the DQS Found Stage of calibration (pi_dqs_found_error=1) as a result of the MRS programming sequence being handled incorrectly.
This is due to the chip select logic always holding chip select (cs_n) Low, causing calibration to continuously program MRS registers which corrupts the MRS sequencing.
