Generalized Parameter Extraction Model for High-Speed Interconnects with Arbitrary Boundary Conditions

An accurate and general interconnect model for planar transmission line interconnects with arbitrary boundary conditions is presented. Based on the unified approach, we develop new SPICE-compatible parameter extraction algorithm that can be used in performance driven computer-aided-design applications. A range of multilayered interconnects with arbitrary boundaries are analyzed. Different ground configurations with respect to the interconnect line are considered for verification of the model. Results are obtained for admittance, line parameters and delay giving physical insights on the effect of boundary conditions. Compared with industry standard fieldsolvers, our proposed model demonstrates more than 10X speedup within 2% accuracy.
