摘要

今天,高速板的路由在很大程度上是一项耗时的手工任务。本文研究了有序逃逸路由问题,这是板级路由中的一个关键问题。所有现有的解决这个问题的方法都不能保证找到一个路由解决方案,即使它存在。提出了一种基于布尔可满足性的精确求解算法。对工业中逃逸路由问题的实验结果表明,该算法具有良好的性能。

Ordered escape routing based on Boolean satisfiability
Routing for high-speed boards is largely a time-consuming manual task today. In this work we consider the ordered escape routing problem which is a key problem in board-level routing. All existing approaches to this problem cannot guarantee to find a routing solution even if one exists. We present an algorithm to exactly solve this problem based on Boolean satisfiability. Experimental results on escape routing problems from industry show that our algorithm performs well.
