Adaptive Sampling Algorithm for Accurate Modeling of General Interconnection Structures

A new adaptive technique is presented for building multidimensional parameterized analytical models for planar interconnection structures with a pre-defined accuracy and based on full-wave electromagnetic (EM) simulations. The models can be incorporated in a circuit simulator and the time required to calculate the circuit representation of a practical network is reduced by several orders of magnitude compared to full EM simulations. Furthermore, the accuracy of the results is significantly better compared to the results obtained with the circuit models used in state of the art CAD tools.
