In the field of reliability and safety, Fault-tree analysis proved to be a useful analytic tool. Aimed at static or dynamic FTs, Monte Carlo simulation based on time-to-failure (TTF) may be an effective way to calculate FTs. Through computing the TTF of bottom events of FTs, the TTF of the system can be calculated easily. However, Monte Carlo simulation based on TTF is time-consuming because modern...
Reliability and availability have always been important characteristics of systems but become even more critical and complex issues on networks. Due to the high complexity of accurate calculation methods, simulation methods for network reliability and availability evaluation have been a popular area of research, and received significant attention. In this paper the network topology model, the failure...
The design of sub-threshold circuits is especially challenging due to the massive impact of process variations. These variabilities also heavily affect circuit timing, a problem only considered concerning combinational gates so far. In this paper the effects of process variations on flip-flop timing at sub-threshold voltages are analyzed based on extensive monte-carlo simulations. The results show...
The impact of process variation on SRAM yield has become a serious concern in scaled technologies. In this paper, we propose a methodology to analyze the stability of an SRAM cell in the presence of random fluctuations in the device parameters. We provide a theoretical framework for characterizing the DC noise margin of a memory cell and develop models for estimating the cell failure probabilities...
