Abstract

Automatic synthesis of analog circuits is being extensively studied and layout parasitics are increasingly being considered in the design loop. Layouts are built either through optimization or by instancing a template. In a circuit synthesis loop, the first approach is very expensive in terms of time complexity and the second one may lead low quality layouts. A better methodology will be to combine these approaches. However, a new type of router is required for such a combination; namely, the template router. This paper presents a template router and discusses how routing is coded and how this code is generated using the well known A* Algorithm.

模板路由器
模拟电路的自动合成得到了广泛的研究,在设计回路中越来越多地考虑布局寄生问题。布局要么通过优化,要么通过实例化模板构建。在电路合成回路中,第一种方法在时间复杂度方面非常昂贵,第二种方法可能导致低质量的布局。更好的方法是将这些方法结合起来。然而,这种组合需要一种新型的路由器;也就是模板路由器。本文提出了一个模板路由器,并讨论了路由是如何编码的,以及如何使用众所周知的a *算法生成这些代码。
