Note: As of version 10.1.02, Xilinx has added a stable EDK export flow to System Generator. The new flow creates a PLB46 slave interface with access to registers, FIFOs and shared memory blocks in the user design. This flow completely replaces sysgen2opb and the OPB Export Tool. As a result, these tools are no longer maintained.
