Why TdiVW_total and VdiVW_total in the External Memory Interfaces IP GUI do not change when selected memory preset speed bin changes?

Environment

  • Intel® Quartus® Prime Pro Edition
  • External Memory Interfaces (EMIF) IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    In the Intel® Quartus® Prime Software, when you access the External Memory Interfaces intellectual property (IP) graphical user interface (GUI) and click on the Mem Timing tab, there are two parameters: TdiVW_total and VdiVW_total. These parameter values do not change when you change the memory device preset. This is incorrect as according to the JEDEC standard and these parameters depend on the memory speed bin.

    Resolution

    You should always provide the TdiVW_total and VdiVW_total values according to the memory device datasheet.
