Introduce the Xilinx Configuration Frame Interface (CFI) for transmitting CFI data packets between the Xilinx Configuration Frame Unit models (CFU_APB, CFU_FDRO and CFU_SFR), the Xilinx CFRAME controller (CFRAME_REG) and the Xilinx CFRAME broadcast controller (CFRAME_BCAST_REG) models (when emulating bitstream programming and readback).
