摘要

本文提出了一种定时和天线比约束下的跳线插入算法。与现有的假设跳线放置在路由树的最高层之上的工作不同,我们的工作允许跳线放置在任何路由层上。此外,我们的算法意识到由跳线引起的延迟。实验结果表明,允许跳线放置在任意层上,跳线所增加的通孔数量可减少50%。实验还表明,我们的时间感知跳线插入算法能更好地满足时间约束。

A jumper insertion algorithm under antenna ratio and timing constraints
In this paper, we propose a jumper insertion algorithm under timing and antenna ratio constraints. Differently from the existing works which assume the jumpers to be placed above the highest layer of a routing tree, our work allows the jumpers to be placed on any routing layer. Furthermore, our algorithm is aware of the delay caused by the jumpers. Experimental results show that, by allowing the jumpers to be placed on any layer, the number of vias added by the jumpers can be reduced by 50%. The experiments also show that our timing-aware jumper insertion algorithm is better at satisfying the timing constraints.
