DRAGON2000: Standard-Cell Placement Tool for Large Industry Circuits

In this paper, we develop a new standard cell placement tool, Dragon2000, to solve large scale placement problem effectively. A top-down hierarchical approach is used in Dragon2000. State-of-the-art partitioning tools are tightly integrated with wirelength minimization techniques to achieve superior performance. We argue that net-cut minimization is a good and important shortcut to solve the large scale placement problem. Experimental results show that minimizing net-cut is more important than greedily obtain a wirelength optimal placement at intermediate hierarchical levels. We run Dragon2000 on recently released large benchmark suite ISPD98 as well as MCNC circuits. For circuits which
