Are the timing violations on the bonding interface of my Cyclone V or Arria V DDR3 bonded hard memory controller design valid?

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    When bonding two DDR3 hard memory controllers in Cyclone® V or Arria® V, you may experience timing violations on the bonding interface. These violations are valid.

    Resolution The workaround is to insert pipeline registers for the bonding signals.
