Efficient, generalized delay and power equations are proposed for large scale CMOS circuit analysis and optimization achieved by transistor and interconnect wire minimization. The proposed model equations are used to analyze the entire power-delay trade-off with less complexity and faster computation time. New equations can be adopted to perform the optimization of transistor and interconnect wire size concurrently. A single stage CMOS circuit and a clock generation block fabricated in 0.48 um CMOS process are given as experimental examples.
