Analysis on the effect of regression and correlation models on the accuracy of Kriging model for IC

摘要

To solve the problem of low efficiency using physical model in circuit simulation, a surrogate Kriging model is introduced and discussed in this paper. Taking the example of an RF amplifier, contrast of effects of different regression and correlation models on the accuracy of Kriging model built is given. Based on analysis of the result, useful strategies for choosing optimal regression and correlation models are proposed.
