HBM2E Controller IIP

HBM2E is full-featured, easy-to-use, synthesizable design, compatible with HBM2E JESD235B and JESD235C with revision 4.10 specification and DFI-version 4.0 or 5.0 specification Compliant. Through its HBM2E compatibility, it provides a simple interface to a wide range of low-cost devices. HBM2E IIP is proven in FPGA environment.The host interface of the HBM2E 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.
