Toward direct EM optimization of VLSI interconnects: validation of coupled transmission line models

With the goal of direct electromagnetic (EM) optimization the authors present results relevant to crosstalk analysis of VLSI interconnects. They employ EM simulators to extract the LC matrices of coupled interconnects to be used in a circuit level simulator. The results are used to validate a set of empirical formulas. The breakthrough concept of space mapping optimization linking EM simulations with empirical formulas is outlined.
