Soft error rate (SER) has become a critical reliability issue for CMOS designs due to continuous technology scaling. However, the striking-time and multi-cycle effects have not been properly considered in SER for advanced CMOS designs. Therefore, in this paper, the striking-time and multicycle effects are formulated into the problem of SER estimation, and then a SER analysis framework is proposed, accordingly. Experimental results show that SERs on the benchmark circuits are seriously underestimated when ignoring both effects. Moreover, SERs increase more on those high-performance or low-power CMOS designs. New treatment to SER needs to be explored in the future.

As the manufacturing technology keeps scaling, crosstalk noise induces a greater impact on timing. Although many previous works proposed techniques like timing correlation, functional correlation and path refinement to consider crosstalk noise during static timing analysis, they often suffered from descendant problems including overly-pessimistic timing bound, bad aggressor selection and false paths. Therefore, in this paper, a coupling-aware functional timing analysis tool named CA-FTA is proposed to tame the three problems stated above and to derive a tighter timing bound for the true longest path. Experimental results show that CA-FTA averagely reduces timing bounds of those obtained from crosstalk STA (with path refinement) by 7.26% on several ISCAS'85 and ISPD-2012 benchmark circuits (in particular, by 34.6% for b19). As a result, CA-ETA successfully solves the aggressor-selection problem as well as the false-path problem and relaxes more margins when considering crosstalk noise.
