Coupled Circuit-Interconnect Modeling and Simulation

In this paper we discuss generating low order models for efficient coupled circuitinterconnect simulation. The ever increasing speeds and shrinking feature sizes that are typical of state of the art integrated circuits designs have made coupling due to interconnect and packaging a very important, sometimes dominant, factor in system performance. The ability to efficiently perform coupled circuit-interconnect simulation before fabrication is essential in order to detect signal degradation due to delays or crosstalk. We first discuss methods of generating models for both two and three dimensional interconnect and then present a general, guaranteed-stable, model order reduction technique to reduce the order of the interconnect models.
