Abstract:Abstract-Traditionally, clock network layout is performed after cell placement. Such methodology is facing a serious problem in nanometer IC designs where people tend to use huge clock buffers for robustness against variations. That is, clock buffers are often placed far from ideal locations to avoid overlap with logic cells. As a result, both power dissipation and timing are degraded. In order to solve this problem, we propose a low power clock buffer planning methodology which is integrated with cell placeme… Show more
