Extracting circuit models for large RC interconnections that are accurate up to a predefined signal frequency

This paper presents a technique that transforms large and complex RC networks into much smaller physically realizable RC networks. These models reflect the transmission behavior of the initial network accurately for frequencies up to a user-defined maximal signal frequency. This technique has been incorporated in a layout-to-circuit extractor, using a scan-line approach. The method guarantees numerical stability and performs excellently in modeling RC interconnects.
