Abstract :
We present both heavy ion and alpha test results for SPARCV8 pipelined-microprocessors fabricated in a space CMOS 65nm platform. Two design implementations, standard and radiation-hardened, are compared at 50/300MHz and 0.8V/1.2V. The dominant failure modes are identified and the failure cross-section is compared with fault injection prediction.
