Why are the Arria 10 DDR4 Mode Register 4 (MR4) write/read preamble bits set incorrectly?


There is a known issue in the Quartus® II software version 13.1 Arria 10 Edition where the DDR4 MR4 write/read preamble bits are set incorrectly.


The issue is fixed in the Quartus II software version 14.0 Arria 10 Edition.
