The advances in VLSI technology have led to complex and larger circuits. As the circuits become complex and large, the amount of time required for the design of such circuits increases. The people in the VLSI industry are looking for faster EDA (Electronic Design Automation) tools so as to reduce the design time. Routing is a phase in the design (physical design) of electronic circuits, wherein...

This paper presents one of the rst attempts to statistically characterize signal delays of basic CMOS digital combinational circuits using the transistor level approach. Hybrid analytical/iterative delay expressions in terms of the transistor geometries and technological process variations are created for basic building blocks. Local delays of blocks along speci c signal paths are combined toge...

|Maximum instantaneous power in VLSI circuits is of great importance to the design of power and ground lines in a VLSI circuit. Underestimating the maximum instantaneous power greatly reduces the circuits reliability. An accurate estimate of the maximum instantaneous power is therefore needed. Unfortunately , nding the input vectors which give the maximum power consumption is a combinational pr...
