HBM2 Controller IP
Overview
HBM2 is full-featured, easy-to-use, synthesizable design, compatible with HBM2 JESD235B specification and DFI-version 4.0 and 5.0 Compliant. Through its HBM2 compatibility, it provides a simple interface to a wide range of low-cost devices. HBM2 IIP is proven in FPGA environment.The host interface of the HBM2 can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
