When you use PFL megafunction in the Quartus® II software to configure Arria® V or Cyclone® V devices in FPPx16 mode, there is a note:
The selected configuration scheme is only supported in Stratix® V device family.
However this note is incomplete. Arria V and Cyclone V devices are supported in this configuration mode.
Resolution You can ignore this note for Arria V or Cyclone V devices. The note will be updated in a future version of the Quartus II software.
