DDR3 Quarter-Rate Is Not Supported for Cyclone V Devices

Environment

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

    Critical Issue

    Description

    This problem affects DDR3 products.

    The user interface incorrectly allows you to select a DDR3 quarter-rate memory interface for a Cyclone V device; however, DDR3 quarter-rate interfaces are not supported for Cyclone V devices.

    Resolution

    The workaround for this issue is to not select a quarter-rate DDR3 interface if you are using a Cyclone V device.

    This issue will be fixed in a future version.
