Abstract
A method and system for reducing the computation complexity and improving accuracy of delay and crosstalk calculation in transmission-lines with frequency-dependent losses. An analysis tool based on restricted coupled-line topologies, simple two-dimensional to three-dimensional RLC matrix conversion, and use of prestored synthesized circuits that accurately capture frequency-dependent loss effects. The CAD tool can handle frequency-dependent resistive and inductive effects for coupled-interconnections on large microprocessor chips with >10K of critical nets. This is done in an interactive manner during the design cycle and allows first path fast product design.
