This work addresses the problem of building accurate and stable parametric macromodels for distributed electronic structures with propagation delays. First, reduced root macromodels are calculated by means of Delayed Vector Fitting technique at estimation points of the design space grid. Then, a suitable interpolation scheme for the delay trends and rational terms is proposed, preserving the model...
We present a new parametric macromodeling technique for lossy and dispersive multiconductor transmission lines (MTLs), that is suitable to interconnect modeling. It is based on a recently introduced spectral approach for the analysis of lossy and dispersive MTLs extended by utilizing the Multivariate Orthonormal Vector Fitting (MOVF) technique to build parametric macromodels in a rational form. They...
The increasing operating frequencies in modern designs call for broadband macromodeling techniques. The problem of computing high-accuracy simulation models for high-speed interconnects is of great importance in the modeling arena. Nowadays, many full-wave numerical techniques are available that provide high accuracy, often at a significant cost in terms of memory storage and computing time. Furthermore,...
