Domain characterization of transmission line models for efficient simulation

Electronic system design requires simulating combinations of lossy, low-loss, frequency dependent, and coupled transmission lines. Accuracy and efficiency considerations would suggest the use of different models and analyses for the various types of interconnects. Toward this goal this paper presents an efficient methodology for characterizing transmission line models into solution domains. Specifically, given an acceptable percentage modeling error, analysis domains are established for automatic model selection between method of characteristics and a lumped modeling approach
