摘要

PROBLEM TO BE SOLVED: To optimize the size of a transistor in combination with the number of turning steps in the design of an integrated circuit. ;SOLUTION: The size of a transistor and the number of turning steps are optimized using a turning model wherein the number of a plurality of turning steps is set to one transistor size. In this turning model, when the lower limit value of the transistor size W is assumbed to be W0 and the height of a layout region is assumed to be H0, the number N of the turning steps can be arbitrarily set in the range of W/H0≤N≤W/W0. By optimizing the size of the transistor along with the number of the turning steps in the range to satisfy a given design constraint using this model, an integrated circuit, which is excellent in the aspects of area and performance, can be designed.;COPYRIGHT: (C)2000,JPO
