    Bus bridges and other odds and ends

  • Yes, I have posted an open source AXI interconnect. Unlike Xilinx's interconnect, mine doesn't automatically bridge between one bus width or clock and another, although some bridges exist in the same repository. Bridges exist, for example, for crossing clock domains, going from AXI3 to AXI4, from AXI4 to AXI4-lite, from AXI4 to a smaller AXI4-lite, and from AXI4-lite to a wider width. It's been enough to keep me from needing my own AXI4 interconnect, although AXI can be a real pain to wire up. As a result, I tend to use AutoFPGA for that purpose.
