ASAP: a transistor sizing tool for speed, area, and power optimization of static CMOS circuits

This paper introduces an automated transistor sizing tool (ASAP) that incorporates accurate gate-level functional models and can be used for delay, area, and power optimization of CMOS combinational logic circuits in a VLSI design environment. The optimization technique is based on simulated annealing and considers the performance improvement of VLSI circuits by optimally sizing the transistors on the N most critical paths.<
