Selected input mode termination value for data bus is not valid. Please select a value of 50 ohm or higher.

Environment

  • Intel® Quartus® Prime Pro Edition
  • External Memory Interfaces Intel® Arria® 10 FPGA IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

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

    • 1.5 V SSTL (DDR3)
    • 1.35 V SSTL (DDR3L)
    • 1.5 V HSTL  (QDRII/II /II Xtreme)
    • 1.2 V SSTL (QDR IV, LPDDR3)
    • 1.2 V HSTL (RLDRAM3)

    Margins improve when values of 50 ohms or higher are selected.
