摘要

路由是集成电路设计中的一个重要步骤,它要求按照设计规则将相关网络以最佳方式连接在一起。布线的重要性在于它对设计的时延和噪声指标的影响。本文对路由的研究进行了概述,并在参考[3]的基础上,通过与其他研究文献的比较和竞争,给出了路由的总体信息流。本文描述了一种通用的路由流程,包括用于路由的通用算法、路由和制造考虑以及角度路由。它表明,路由不需要任何复杂的数学,而是基于一些在不同学科中常见的算法,并对其进行了讨论和解释。另一方面,启发式估计的精确选择是路由成功的关键因素。

Routing's algorithms and considerations
In routing, which is an important step in designing an IC, related nets should be connected together in the best way according to the design rules. The importance of routing is due to its effect on delay and noise specification of the design. An overview on routing is presented in this paper, which overall flow of the information are base on reference [3] and by comparing and competing in other research papers. In this paper a general routing flow is described by common algorithms used for routing, router and fabrication considerations, and also angled routing. It's shown routing does not need any complicated mathematics but based on a few algorithms that are common in different subjects which are discussed and explained. On the other hand the precise selection of heuristic estimations acts as a crucial factor in success of routing.
