Domain Decomposition via Electromagnetic Hooks for the Modeling of Complete RF blocks

Abstract

To cope with the complexity and size of modern RF SoC designs, a new type of domain decomposition has been developed that makes use of electric and magnetic connectors. This new concept has been tested on a number of practical examples that are all produced and measured within the project. To illustrate the success of the algorithm, it is applied to a set of coupled integrated inductors, and results are compared with measurements and simulations using tools from MAGWEL and Agilent (Momentum). Domain decomposition is a powerful method to enable accurate electromagnetic simulation of complex, large layouts. The accuracy / simulation speed trade off is conveniently controlled by the number of hooks on the decomposition interface.
