Due to current technology scaling trends such as shrinking feature sizes and decreasing supply voltages, circuit reliability is becoming more susceptible to radiation-induced transient faults (soft errors). Soft errors, which have been a great concern in memories, are now a main factor in reliability degradation of logic circuits as well. In this paper, we present a systematic and integrated methodology for circuit robustness to soft errors. The proposed soft error rate (SER) reduction framework, based on redundancy addition and removal (RAR), aims at eliminating those gates with large contribution to the overall SER. Several metrics and constraints are introduced to guide the RAR-based approach toward SER reduction. Furthermore, we integrate a resizing strategy into our framework, as post-RAR additive SER optimization. The strategy can identify most critical gates to be upsized and thereby, minimize area and power overheads while maintaining a high level of soft error robustness. Experimental results show that the proposed RAR-based framework can achieve up to 70% reduction in output failure probability. On average, about 23% SER reduction is obtained with less than 4% area overhead. |
