The partial element equivalent circuit method (PEEC) has been popularly used for signal integrity and power integrity. Its port setup usually only includes conductive effects in the format of current sources or voltage sources. However, its radiation effect was neither included nor studied. In this paper, for the first time we provide novel solutions to approximate the radiation contributions from...
Electromagnetic radiations from parasitic structures such as electronic interconnections are very difficult to diagnose because the ability to identify the specific sources are missing. Mainly, the source of radiations cannot be identified separately. Here, the partial element equivalent circuit (PEEC) method is extended to diagnose the radiation and its distribution. For the first time we identify...
Proper power integrity analysis is required for printed circuit board (PCB) power distribution network (PDN) design. Developing a simple physics-based equivalent circuit model for critical structures is essential for understanding the physics of the system and for intelligent designs. In this paper, a physics-based model size reduction (PMSR) method is applied to get the equivalent circuit model for...
The stability issues for time domain integral equations is well known and it has been investigated for a long time. In this paper, we pursue an approach for the stabilization and even passivization of the electromagnetic solutions in the time and frequency domain using the PEEC circuit techniques. We aim to enhance the passivity by adding more passivization to the EM solution rather than using a post-processing...
The computation of the power-plane inductance for multiple ports is an important part of the PDN design. In this paper, we present an efficient approach for the inductance computation. Since this PEEC approach is based on partial inductance computations, vias and other discontinuities can accurately be taken into account. Speed-up techniques are employed like the faster decay of the coupling due to...
In this paper we consider the skin- and radiation effects for a thin wire segment. Circuit models are being constructed which are suitable for the modeling of thin wires like the wire bonds. We use the internal-external inductance model for this purpose of including the skin-effect in the partial inductance. These models make it possible to include thin, round conductors in a PEEC model at a much...
A challenging issue for the solution of large electromagnetic problems is the efficient modeling of the broadband skin-effect for conducting planes and 3D shapes. The inclusion of such models in an EM solver can be very costly in compute time and memory requirements. Progress has recently been made in the design of skin-effect models. Several properties of a model are desirable for the solution of...
We present a new model order reduction technique for electrically large systems with delay elements, which can be modeled by means of neutral delayed differential equations. An adaptive multipoint expansion and model order reduction of equivalent first order systems are combined in the new proposed method that preserves the neutral delayed differential formulation. An adaptive algorithm to select...
We propose a novel model order reduction technique that is able to accurately reduce electrically large systems with delay elements, which can be described by means of neutral delayed differential equations. It is based on an adaptive multipoint expansion and model order reduction of equivalent first order systems. The neutral delayed differential formulation is preserved in the reduced model. Pertinent...
New algorithms are needed to solve electromagnetic problems using today's widely available parallel processors. In this paper, we show that applying the optimized waveform relaxation approach to a partial element equivalent circuit will yield a powerful technique for solving electromagnetic problems with the potential for a large number of parallel processor nodes.
