Non-Gaussian Statistical Timing Analysis Using Second-Order Polynomial Fitting

Correlation-Preserved Non-Gaussian Statistical Timing Analysis with Quadratic

Recent study shows that the existing first order canonical timing model is not sufficient to represent the dependency of the gate delay on the variation sources when processing and operational variations become more and more significant. Due to the nonlinearity of the mapping from variation sources to the gate/wire delay, the distribution of the delay is no longer Gaussian even if the variation...

Fitting the Fractional Polynomial Model to Non-Gaussian Longitudinal Data

As in cross sectional studies, longitudinal studies involve non-Gaussian data such as binomial, Poisson, gamma, and inverse-Gaussian distributions, and multivariate exponential families. A number of statistical tools have thus been developed to deal with non-Gaussian longitudinal data, including analytic techniques to estimate parameters in both fixed and random effects models. However, as yet ...

Anthropometric Analysis of Face using Local Gaussian Distribution Fitting Applicable for Facial Surgery

Human facial plays a very important role in the human’s appearance. Many defects in the face affect the facial appearance, significantly. Facial plastic surgeries can correct the defects on the face. Analysis of facial color images is very important due to its numerous applications in facial surgeries. Different types of facial surgeries, such as Rhinoplasty, Otoplasty, Belpharoplasty and chin ...

Parameterized Block-Based Statistical Timing Analysis with Non-Gaussian Parameters and Nonlinear Delay Functions

Variability of process parameters makes prediction of digital circuit timing characteristics an important and challenging problem in modern chip design. Recently, statistical static timing analysis (statistical STA) has been proposed as a solution. Unfortunately, the existing approaches either do not consider explicit gate delay dependence on process parameters [3] [6] or restrict analysis to l...
