Previous results and models have predicted that combinational logic errors would dominate over flip-flop errors for the past few technology nodes. However, recent experimental results show very little contribution from combinational-logic soft errors to overall soft-error rates. A model that explains the soft error rates as a function of frequency is developed to account for the inconsistency in observed data. Implications for hardening against soft errors for advanced technologies are discussed.
