This paper describes reliability assessment from measured data of double-stress accelerated degradation test which taking functional unit as research object. Most of performance degradation reliability analyses pay attention to components. Thereby assessments are relatively easy because they have simple function and clear failure mechanism. However, in reality, functional units compose system, and...
Current design and optimization of a flight control actuator system is based on a traditional design theory and sophisticated methods to get stable and good performance ability, but designed scheme may be sensitive to the environment fluctuation, internal parameter variation and component catastrophic failure. Reliability of actuator system is the ability that system can satisfactorily implement its...
Sub-threshold operation is a compelling approach for energy-constrained applications, but increased sensitivity to variation must be mitigated. We explore variability metrics and the variation sensitivity of stacked device topologies. We show that upsizing is necessary to achieve robustness at reduced voltages and propose a design methodology to meet yield constraints. The need for upsizing imposes...
In this paper, we propose a novel methodology for statistical SRAM design and analysis. It relies on an efficient form of importance sampling, mixture importance sampling. The method is comprehensive, computationally efficient and the results are in excellent agreement with those obtained via standard Monte Carlo techniques. All this comes at significant gains in speed and accuracy, with speedup of...
The performance of Hebbian-type associative memories (HAMs) in the presence of faulty interconnections is examined, and equations for predicting network reliability are developed. Several HAM operating modes, i.e. zero or nonzero autoconnections (ZA or NZA), bipolar or unipolar network inputs, asynchronous or synchronous operation, have been investigated. Networks with NZA and bipolar inputs have...
