GRSCRUB is an FPGA supervisor responsible for programming and scrubbing the FPGA configuration memory to prevent the accumulation of radiation-induced errors. The GRSCRUB IP currently supports the AMD/Xilinx Kintex UltraScale and Virtex-5 FPGA families.
The GRSCRUB is an external FPGA configuration monitor that features programming and scrubbing capabilities. After the initial configuration, the GRSCRUB is self-standing, which releases the processor core to perform other tasks. The GRSCRUB is compatible with the AMD/Xilinx Kintex UltraScale and Virtex-5 FPGA families. It accesses the target FPGA configuration memory externally through the SelectMap interface. GRSCRUB is intended to be used as an external entity to the FPGA being supervised.
