This paper presents an FPGA fault injection system, a methodology for soft processor fault injection, and fault injection experimental results for MicroBlaze and LEON3 soft processor designs. The Xilinx Radiation Test Consortium—Virtex 5 Fault Injector (XRTC-V5FI) was built to evaluate the configuration memory sensitivity of soft processor designs. To overcome some of the challenges of soft processor fault injection, we designed the XRTC-V5FI to be fast, flexible, and to fully cover all configuration memory bits. The minimum time to inject a full bitstream is 28 minutes and the individual fault injection can be as fast as 49 μS. The LEON3 has 81.3 % more sensitive bits than the MicroBlaze, yet when normalized by the number of used slices, the MicroBlaze is 26.2 % more sensitive than the LEON3.
