Abstract
Standard cells are essential components of modern digital circuit designs. With process technologies advancing beyond 5nm, more routability issues have arisen due to the decreasing number of routing tracks (RTs), increasing number and complexity of design rules, and strict patterning rules. The standard cell design automation framework is able to automatically design standard cell layouts, but it is struggling to resolve the severe routability issues in advanced nodes. As a result, a better and more efficient standard cell design automation method that can not only resolve the routability issue but also scale to hundreds of transistors to shorten the development time of standard cell libraries is highly needed and essential.
