Abstract :
This paper presents a novel W-shape multilevel full-chip routing framework. The framework features the W-shape optimization flow. The first V-shape flow aims to optimize the global routing solution. And the second V-shape flow intends to improve the quality of the detailed routing result. The framework is tested on a set of commonly used benchmark circuits and compared with the previous multilevel routing systems. The experimental results are promising
