摘要

描述了一种利用层分配的重叠模型实现两层路由的新方法。重叠模型允许轨道在实际设计规则允许的情况下相互叠加。该技术非常简单和优雅，其结果比定向模型下的最优解更加紧凑，并且每个子网最多有一个通道。这里在蜂窝信道路由的上下文中进行了说明。

An overlap model for routing

Describes a new approach to routing in two layers using the overlap model of layer assignment. The overlap model allows tracks to be laid on top of each other as permitted by the real design rules. The technique is very simple and elegant with results more compact than the optimal solutions under the directional model and with at most one via per subnet. It is illustrated here in the context of over-the-cell channel routing.<>
