Abstract

We are the first to develop SPICE compatible circuit model for partial reluctance K. It can be combined with any partial reluctance based extraction method to perform RLC sim ulationdirectly without the need of inverting partial reluctance matrix back into partial inductance domain or modifying conventional simulator.To build symmetrical partial reluctance matrix, we also proposed blocked K method based on group concept to cover more magnetic couplings. Both quantitive analysis and experiments demonstrated that the combination of the SPICE compatible circuit model and the blocked K method has the best compromise between accuracy and performance among all SPICE compatible sparsification techniques.
