“…In reference to linear time-invariant passive components/circuits, extracted macro-models based on rational function approximations could face stability and passivity preservation problems. The stability condition imposes that the poles of the extracted macro-model lie on the left half-part of the s-plane [6] while, the passivity preservation condition ensures, for a passive circuit, to not generate energy (amplification/oscillation phenomena) [19][20][21][22] as discussed in the Appendix.…”

“…In the case of extracted synthesis elements given in Table I Such criteria (A-10) and (A-11) are easy to verify for passivity preservation checking, however enforcing passivity once the criteria is violated requires efficient techniques. In [19][20] a post-processing perturbation technique combined with linearization procedure is used for passivity enforcement while in [22] perturbation of Hamiltonian matrix is proposed.…”

A partition-recomposition methodology based on internal port concept associated to auxiliary sources, is proposed for electromagnetic (EM) analysis of SiP (SystemIn-Package) Off-chip and On-Chip passive circuitry towards optimized passive and active frequency and time domain cosimulation. Attributes of internal ports and associated deembedding procedures for local ground references are discussed. Application of the proposed methodology to offchip SiP multi-conductors and functional components is presented. A broadband extraction methodology is applied to derive, from EM simulation results or measurement data of passive structures, Spice-compatible models for transient/SSN (Simultaneous Switching Noise) analysis.

This paper presents a compact passive model of multiconductor transmission lines (MTLs) with frequencydependent parameters. The development of this model is based on the generalized equivalent circuit model of MTLs where the original frequency-dependent RLCG parameters are transformed into frequency-independent ones. This model can be easily embedded into the discrete transmission line model based on compact finite difference scheme, and the precise time-step integration method is used to solve them in the transient analysis. In addition, since the passivity of the compact model is preserved, it is also compatible with the passive model order reduction algorithm. A numerical example is presented to demonstrate the validity and accuracy of the model.

“…Traditionally, modeling of high-speed distributed networks have been based on the assumption that the model parameters are either known constants [1][2][3][4][5][6] or varying in a deterministic fashion [7][8][9]. However, with the constant drive towards greater miniaturization and stricter design criteria, parameter variation of high-speed distributed networks induced by manufacturing processes, temperature variability, and EM environment are random in nature and cannot be studied accurately using deterministic approaches [10].…”

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.
