Webacademic routability-driven placers. 1. INTRODUCTION Placement is one of the most important and ancient prob-lems in Electronic Design Automation (EDA). Its quality has been greatly improved during the last two decades. How-ever, with the gradually increasing scale of design, a high quality while extremely fast placer is still in urgent need. WebHowever, design routability has emerged from a secondary objective to perhaps the primary objective, in no small part due to the myriad of rules and constraints that emerge with each successive technology. This work overviews the complexities with modeling congestion during physical synthesis and discusses how optimizations may be able to ...

For example, a global routing solution with an overflow of 700 might still be routable, as the overflow could be absorbed by neighboring regions or resolved during the subsequent routing phases. Further, their lack of intuition (e.g., how good/bad is an overflow of 14;253?) makes it difficult to quantify how much
