A novel methodology for accurate and efficient static timing analysis is presented in this paper. The methodology is based on finding a frequency domain model for the gates which allows uniform treatment of the gates and interconnects. It is shown that despite the highly nonlinear overall gate model, a frequency domain model of the gate with the model parameters, gate moments, as functions of the...
Focusing on nonlinear/non-Gaussian filters and based on analysis of the sampling-importance-resampling algorithm, this paper examines principles and application of particle filter (PF) in satellite orbit determination. There may be large error of initial estimation and non-Gaussian distribution of state and measurement in satellite orbit determination. To solve the two problems, an improved PF algorithm...
