This document provides the user guide for Altera's External Memory PHY Interface (ALTMEMPHY) (nonAFI) Megafunction. The document includes information about the software version, copyright information, trademark information, and warranty terms of the product.
The ALTMEMPHY megafunction serves as an interface between a memory controller and memory devices, performing read and write operations. It is available as a stand-alone product or integrated with Altera high-performance memory controllers. This specific guide focuses on the non-Altera PHY interface (nonAFI) variations and QDR II+/QDR II SRAM interfaces for legacy designs.
The document details parameter settings for the megafunction, including memory presets and PHY settings. It also provides a functional description of the initialization timing, signal definitions for DDR2/DDR SDRAM and QDR II+/QDR II SRAM, and the calibration process. Additionally, it covers design considerations such as clock management, handshake mechanisms, and support for specific device families like Arria GX and Stratix II.

It is an interface between a memory controller and memory devices that performs read and write operations to the memory.
The nonAFI variation should only be used for legacy designs, as the AFI is recommended for new designs.
This guide describes the specifications for the ALTMEMPHY (nonAFI) megafunction with QDR II+ and QDR II SRAM interfaces.
