Modeling and layout optimization of VLSI devices and interconnects in deep submicron design

This paper presents an overview of recent advances on modeling and layout optimization of devices and interconnects for high-performance VLSI circuit design under the deep submicron technology. First, we review a number of interconnect and driver/gate delay models, which are most useful to guide the layout optimization. Then, we summarize the available performance optimization techniques for VLSI device and interconnect layout, including driver and transistor sizing, transistor ordering, interconnect topology optimization, optimal wire sizing, optimal buffer placement, and simultaneous topology construction, buffer insertion, buffer and wire sizing. The efficiency and impact of these techniques will be discussed in the tutorial.
