HBM2 Controller IP

Description and Features

HBM2 is full-featured, easy-to-use, synthesizable design, compatible with HBM2 JESD235 and JESD235A specification and DFI-version 4.0 or 5.0 specification Compliant. Through its HBM2 compatibility, it provides a simple interface to a wide range of lowcost devices. HBM2 IP is proven in FPGA environment. The host interface of the HBM2 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.
