DDR3 Quarter-Rate Is Not Supported for Cyclone V Devices - DDR3 Quarter-Rate Is Not Supported for Cyclone V Devices 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.
