    • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    In the Quartus® II software version 13.1 Arria® 10 edition, you may see this error when selecting a CAS Write Latency of less than 9 cycles in Mode Register 2 in the Arria 10 DDR3 IP GUI.

    There is a restriction in the ES devices that requires the CAS Write Latency be set to 9 cycles or greater.
