The layout of integrated circuits on chips and boards (physical design) is one of many interrelated complex tasks in VLSI circuit design. A major portion of the research in the area of design automation has been devoted to the development of efficient and easy-to-use systems that support circuit layout. Today's embedded systems contain various combinations of different components in the form of microprocessors, memories and application specific integrated circuits (ASICS). All this cannot be achieved without advanced and suitable CAD tools including physical design automation. The interconnect delay in VLSI circuits has become a critical determiner of circuit performance. It seems to become more and more important to know the impact of interconnection on speed and power consumption early in the design trajectory of high-performance processors and Systems-on-Chip. As a result, circuit layout is starting to play a more important role in today's chip designs.
