“…(p)) by a factor of (P + 1). Consequently, the time complexity of the classical VF approach to obtain the macromodel Y(t) will scale very poorly as O(P 4 p 4 ) [13]. To address this poor scalability of existing macromodeling techniques, a more efficient alternative macromodeling methodology based on the Loewner matrix (LM) interpolation method is proposed.…”

“…This augmentation in the number of network ports is a major bottleneck in the efficient development of time-domain macromodels since the computational complexity of conventional macromodeling strategies such as those based on the classical Vector Fitting (VF) algorithm [12] scale extremely poorly with the overall number of network ports [13]. Most recently, an alternative macromodeling algorithm based on Loewner Matrix (LM) approach has been proposed with significantly better scaling with respect to number of ports over the VF based approaches for the case of deterministic problems [5,6,14].…”

Distributed networks with embedded parametric uncertainty can be characterized in the frequency-domain by tabulated augmented multiport S or Y -parameter responses based on a stochastic Galerkins formulation of the network equations. In this work, the Loewner Matrix approach is utilized to generate a compact SPICE-compatible macromodel of the stochastic distributed network from the tabulated frequencydomain data for transient analysis. The key attribute of this work is that the superior scaling of the computational complexity of the Loewner Matrix approach with respect to the augmented number of network ports allows for a more efficient generation of the macromodel than the classical Vector Fitting approach. This leads to faster transient analysis for problems involving large random spaces. The advantage of the proposed approach is validated using a numerical example.

“…Recent works aimed at quantifying the transverse EM coupling are based on transmission line models for coupling through narrow slots [22] and analytic models based on the Green's function [23]. These models provide a frequency domain solution only and may need an additional post processing like rational curve fitting with passivity enforcement [24]- [25] or numerical convolution [26] for transient analysis.…”

Typical modeling algorithms for multilayered irregular shaped power distribution networks are based on a finite difference solution of the Helmholtz equation. In this paper, the finite difference solution is demonstrated to be equivalent to a discretization of the Telegraphers partial differential equations for multiconductor transmission lines (MTL). With this concept, an efficient macromodeling algorithm for multilayered structures based on MTL theory is presented. The electromagnetic coupling between the plane layers due to wraparound currents is captured by the inductive and capacitive coupling between the multiconductor lines. A delay extraction-based macromodel is used to represent the MTL in SPICE that can better capture the distributed effects of the structure than existing lumped models. This approach is successfully implemented for multilayered structures with irregular geometries and is shown to be more accurate and efficient compared with existing SPICE lumped models.Index Terms-Delay extraction, dispersion, power distribution networks (PDN), simultaneous switching noise, skin effect, transmission lines, wraparound current.
