Interconnect effects dominate performance and power in the Deep Submicron regime, and Computer Aided Design tools and methodologies need to focus more on interconnect optimization. In addition, there is a push for dramatic levels of on-chip integration in modern circuits. The cumulative effects of the two make design of leading-edge electronic products difficult. In this work, we propose improved techniques and methodologies for layout design of modern VLSI chips. These techniques can be classified as floorplanning, mixed-size placement and VLSI placement for physical synthesis. The proposed algorithms address novel problem formulations and design concerns that arise in modern VLSI designs.
