Abstract(in English) In recent years, the probability of soft errors has been increasing due to the miniaturization, high integration, and low operating voltage of VLSI, and this has become a problem at the ground level. Soft errors are temporary failures that occur in circuits and are caused by neutrons and alpha particles contained in radiation. The soft errors are caused by neutrons and α-particles in the radiation, and are a problem because transient currents are generated when the radiation hits the VLSI, causing a value reversal when the critical charge level is exceeded. To date, various soft-error tolerance techniques have been proposed, but since master-slave D-FFs are the mainstream due to the ease of D-latch fabrication, the proposed soft-error tolerance designs are often latch-based. In this paper, we propose a structure that applies the complementarity of the DICE to edge-triggered D-FFs, and compare it with master-slave D-FFs using the DICE. The results show that the proposed circuit is useful in terms of soft error tolerance, power consumption, and setup time.
