Abstract :
This paper shows a generalized optimizer that interacts with an external circuit simulator to extract frequency-dependent lossy coupled transmission line models from TDR or VNA measurements. The optimizer´s architectural flow, and such concepts as global and local iterations, weighting function, time-windowing and piecewise-linear source models are mentioned. Several examples, including a complex BGA package model, are used to demonstrate its effectiveness in extracting model parameters and correlating waveforms
