Balanced stochastic truncation of coupled 3D interconnect

Model order reduction techniques have been used extensively to reduce the complexity of extracted interconnect circuits and to expedite fast and accurate circuit simulation. In this paper, we introduce a balanced stochastic truncation in model order reduction of a coupled 3D interconnect to provide uniform approximation of the frequency response of the original system over the whole frequency domain. As the experimental results indicate, the proposed approach can significantly reduce the complexity of interconnect, while retaining high accuracy in comparison to the original model.
