A circuit-level layout-aware single-event simulation capability is presented. Multiple 40-nm bulk CMOS flip-flops are analyzed to determine single-event upset (SEU) sensitive area. Comparisons between simulation results and broadbeam heavy-ion test data show excellent agreement. Simulations of single-event strikes over the entire flip-flop layout can be performed in less than 1 h.
