A New Methodology for Early Stage Magnetic Modeling and Simulation of Complex Electronic Systems

This paper presents a new methodology called Flex-CM for Flexible Compact Modeling to generate and reuse compact models, in order to build a full model of a complex electronic system at an early stage of the design flow. The system is split into independent parts. Each part is numerically modeled using a discrete approach then reduced to save memory and time at the simulation stage. The resulting pluggable and reduced model is called a micro-model. Then, a fast-to-simulate macro-model of a full system can be obtained by assembling the micro-models. The Flex-CM model is presented as a trade-off between reluctance networks and numerical models to perform a magnetic analysis at an early stage of the system design. The Flex-CM models are found to have number of advantages over both methods, resulting however on larger models than reluctance networks.
