Abstract:During recent years, the VLSI technology has advanced profoundly, which is in urgent need of strong support from high performance integrated circuit (IC) CAD tools, that is, electrical design automation (EDA) software environment. The technology of VLSI computer aided physical design is called layout design. Global routing is a significant part of layout design. With progress in VLSI, ultra large scale integrated circuits (ULSI) deep submicron (DSM) and very deep submicron (VDSM) technology, many new problems need to be solved in global routing. To solve these problems, many methods in global routing have been proposed to improve the chip performance. Performance-Driven global routing technology has been an active area of research. As a result, the key technologies to be studied urgently in performance-driven global routing are analyzed in detail in this paper. The corresponding research work and the important results in this reserch field are also given.
Keywords:global routing  ultra large scale integrated circuits (ULSI)  very  deep  submicron (VDSM)  timing  crosstalk
