    • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    You may see the above error starting with Quartus Prime software version 16.1.1 if your EMIF IP uses input termination below 50 ohms for the following I/O standards:

    • 1.5V SSTL (DDR3)
    • 1.35V SSTL (DDR3L)
    • 1.5V HSTL  (QDRII/II /II Xtreme)
