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

Description

Although the Arria® V handbook states that the A1, A3, A5, and A7 devices can 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.

Resolution

Please follow the document to set the data width up to 32 bits.
