Why can I assign more than a 32-bit data width to the Arria V Hard Memory Controller ?


Although the Arria® V handbook states that the A1, A3, A5 and A7 devices have the capability to support up to a 32-bit width controller on top or bottom edges, the Quartus® II software incorrectly allows you to implement a 40-bit controller without an error message.



This issue is scheduled to be fixed in a future release of the Quartus II software.
