Efficiency Monitor Not Usable With Arria V or Cyclone V Hard Memory Interface - Efficiency Monitor Not Usable With Arria V or Cyclone V Hard Memory Interface Resolution The workaround for this issue is to use Qsys to generate the external memory interface IP without the Efficiency Monitor, and then generate the Efficiency Monitor separately. You can then enable the Efficiency Monitor for your interface by connecting the Avalon interfaces manually. This issue will be fixed in a future release. Related Articles This problem affects DDR2, DDR3, and LPDDR2 products. For designs targeting the hard memory interface on Arria V or Cyclone V devices, an attempt to use the Efficiency Monitor will result in an error message in the MegaWizard Plug-In Manager.
