DDR4 is full-featured, easy-to-use, synthesizable design, compatible with DDR4 JESD79-4, JESD79-4A, JESD79-4A_r2, JESD79-4B, JESD79-4C and JESD79-4D (Draft) specification and DFI-version 3.0 or higher Specification Compliant. Through its DDR4 compatibility,it provides a simple interface to a wide range of low-cost devices. DDR4 IIP is proven in FPGA environment.The host interface of the DDR4 can be simple interface or can be AMBA AHB, AMBA AHB-Lite, AMBA APB, AMBA AXI, AMBA AXI-Lite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or Custom protocol.
DDR4 Controller IIP is supported natively in Verilog and VHDL
