Minimal-order multi-dimensional linear interpolation for a parameterized electromagnetic model database

We present a minimal-order multi-dimensional linear interpolation schema used to interpolate in an N-dimensional EM model database. The EM model database is used to link a computation time expensive EM simulator with a general purpose circuit simulator. The EM model database enables fast EM/Circuit co-simulation, co-optimization and the simultaneous tuning of lumped component elements and distributed layout parameters. The interpolation scheme is minimal-order in the sense that it minimizes the number of samples needed to perform the multi-dimensional linear interpolation. The accuracy and computational efficiency of the proposed modeling technique are validated through different circuit simulation examples.
