Abstract (in Japanese) (See Japanese page) 
(in English) Clock gating is an effective technique to reduce dynamic power consumption for sequential circuits. This paper shows a sharing method of clock gating logic under multi-stage clock gating control. By sharing the clock gating logic, the total activity of registers and clock gating modules can be reduced. The method is implemented based on BDD and is applied to counters and a set of benchmark circuits. There have been found on average 23.0% cost reduction by the proposed multi-stage clock gating generation method. The power estimation using layout data will also be shown.
