GDDR6X interface provides full support for the GDDR6X interface, compatible with GDDR6X protocol draft specification and DFI-version 4.0 or 5.0 Specification Compliant. Through its GDDR6X compatibility, it provides a simple interface to a wide range of low-cost devices. GDDR6X IIP is proven in FPGA environment. The host interface of the GDDR6X 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.
GDDR6X Controller IIP is supported natively in Verilog and VHDL
