This work will present a method for the efficient description of independent sources in electrical networks for a model reduction. The number of ports of the model is reduced with the help of controlled sources and the resulting network is passive and reciprocal. The model is then reduced with model order reduction methods. The lower number of ports hereby allows for a higher reduction. Passivity...
This paper introduces an efficient description of electromagnetic macromodels that contain passive electrical elements and a large number of independent sources. This description allows for much higher order reduction than the standard description. In the proposed description the behavior at the pins of the model as well as the passivity are preserved. With model order reduction algorithms the proposed...
This paper addresses the order reduction of IC conducted emission models. These models are mathematically described by singular matrices of high order. Usually the order of the matrices can be reduced by the multipoint Krylov based order reduction. To achieve an even lower order we introduce a two step order reduction. The first step is the order reduction method based on the multipoint approximation...
This work will present a method for the efficient description of a large number of independent sources in electrical networks for a model order reduction. With the help of controlled sources, the number of ports is reduced, which enables a high order reduction. The proposed description guarantees the passivity and reciprocity of the system, which are preserved in the order reduced system. Synthesizing...
This paper presents the abstract modelling of packages and high density interconnections, in order to build a behavioral model knowing very few information. The approach is based on combining black box modelling and order reduction. The package is divided into single block models that are defined from arbitrary input and output signals. Using black box modelling numerically effective simulations of...
As wiring density increases with integration and miniaturization of systems and PCB (for example SiP), the ability to simulate precisely the signal integrity (SI) behaviour of complex systems becomes decisive, while the simulation time increases dramatically. Therefore it is essential that the design of such complex systems is supported by accurate simulation models. This paper proposes a methodology...
