Specifies the local side interface between the user logic and the memory
controller. The Avalon Memory-Mapped (MM) interface allows you to
easily connect to other Avalon-MM peripherals.
Specifies the controller/PHY interface. Refer to the
PHY Interface Megafunction User Guide (ALTMEMPHY)
information.
This option is only in SOPC Builder Flow. Turn on if you want to improve
