Blind Scrubbing For Xilinx KU060 FPGAs

This reference design program adds blind scrubbing capability to Xilinx’s Kintex® UltraScale™ XQRKU060 FPGA configuration memory. The program adds further mission assurance by ensuring that the FPGA configuration image is continually refreshed. The scrubber program resides on a UT32M0R500 microcontroller and scrubs the KU060 FPGA’s configuration memory by blindly overwriting the existing configuration with a predetermined image at a pre-specified refresh rate.
