Nanoscale VLSI systems are subject to increasingly significant performance variability. Accurate timing analysis and effective silicon-based performance verification techniques are critical to successful nanoscale VLSI design. The state-of-the-art statistical static timing analysis (SSTA) techniques cannot capture performance variability due to primary inputs and sequential element states which, however,...
Estimating the dynamic powers is crucial for power and energy efficient chip designs. With increasing variability from manufacture processes, dynamic powers can manifest significant variations due to uncertainties in device geometry and delay variations. In this paper, we propose a new statistical dynamic power estimation method considering the spatial correlation in process variation. We first show...
Recognition distance in urban space is affected by many factors. Based on the relevant factors, this paper sums up those which affect urban distance cognition in the travel mode of bus, and conducts a cognitive test to get people's recognition data. We make some quantitative analysis of these data in the use of statistical methods. The results show that: in the bus travel mode, recognition distance...
