Book excerpt: With the increase in signal speeds in VLSI systems, distributed effects arising in passive components such as high speed interconnects and power distribution networks are the main contributors of signal and power degradation at chip, package and board levels. As a result computer aided design strategies targeting modeling and simulation of such high speed systems at the early design stages are critical requirements for VLSI designers. However, the computational demand of accurately capturing the distributed nature of such components is a major bottleneck facing traditional circuit solvers. This thesis deals with two different approaches towards modeling of high speed distributed networks. One approach deals with cases where the physical characteristics of the network are not available and the network is characterized by its frequency domain, multiport tabulated data. The other approach is based on a detailed knowledge of the physical and electrical characteristics of the network and assuming a quasi transverse mode of propagation of the electromagnetic wave through the network. In the first part of the thesis, a delay extraction based IFFT algorithm is described for the accurate macromodeling of electrically long interconnect networks characterized by its frequency domain, multiport Y parameter data. An important feature of this work is the ability to extract the higher order delays and the associated attenuation losses embedded in the data via time-frequency decompositions. The effect of including the higher order delays have been shown to lead to greater accuracy over existing direct IFFT or even single delay extraction based IFFT techniques for transient simulation.
