Due to a problem with the Frame Buffer II IP Core prior to Quartus® Prime Software version 17.0, you will see this behavior if you select the 128 bit Avalon®-MM master(s) local ports width.
Device Family: Intel® Arria® 10, Arria® II, Arria® V, Cyclone® IV, Cyclone® V, Intel® MAX® 10, Stratix® IV, Stratix® V
Area: Intellectual Property
To work around this problem, select the 256 bit local ports width. Qsys® will automatically insert a width adapter if you need to connect to other 128 bit slaves.
This problem has been fixed starting in the Quartus Prime software version 17.0.
