Present statistical techniques estimate the average power based on the assumption that the power distribution can be characterized by a preassumed function. Large errors can occur when the assumption is not met. To overcome this problem, we propose a nonparametric technique in which no distribution function needs to be assumed. A distribution-independent upper and lower bound of the average power are derived from the Kolmogorov-Smirnov theorem. A stopping criterion is designed based on the bounds for a desired percentage error with a specified confidence level. Since it does not resort to the assumption of any particular distribution function, the technique can be applied to all the circuits irrespective of their power distributions.","PeriodicalId":74515,"journal":{"name":"Proceedings of the ...

They need a fast power estimation capability which gives reasonably accurate power estimates. In this paper, we present some ideas to obtain an efficient implementation of probabilistic power analysis for combinational circuits. These ideas are based on the observation that in order to obtain a fast implementation, it is very important to control the sizes of the Reduced Ordered Binary Decision Diagrams (ROBDDs) that are created during analysis. However, controlling sizes of ROBDDs could impact the accuracy of the result. We explore the consequences of making the trade-off between performance of the implementation and accuracy. Our experimental results illustrate that our implementation can provide estimates that are within 5% of a commonly used probabilistic method and runs 10 times faster, on average. Our method also scales very well for large circuits.","PeriodicalId":74515,"journal":{"name":"Proceedings of the ... Custom Integrated Circuits Conference.

Unlike existing circuit-level electrothermal simulators, it finds the steady-state temperature distribution, the hot spots, as well as the resulting power consumptions in an extremely efficient way. By using a fast timing simulator with accurate temperature-dependent device models and a novel 3-D analytical thermal simulator, it can easily handle very large circuits. With iTHREAD, temperature-dependent reliability and timing problems of VLSICs can be accurately and quickly predicted. It can be further applied to guide the module placement, timing verification, and many other IC reliability diagnoses.","PeriodicalId":74515,"journal":{"name":"Proceedings of the ...

The small programmable Flash switching element facilitates use of a fine grain architecture optimized for design techniques based upon high level design and synthesis. At 0 . 8 ~ technology, the largest member of the family is rated at 100,000 gates.

The former is shown to be replaceable, without restrictions, by non-orthogonal decoding, which is also shown to increase routability.
