摘要

矩形二值化是集成电路自顶向下平面规划中产生矩形拓扑的一种方法。作者提出了一种有效的算法,将表示自定义集成电路的任意图转换为适合矩形二象化的图。该算法采用了平面嵌入等有效的图处理技术,并引入了一种新的方法,将双连通子图树转换为具有路径的块邻域图。

Automatic building of graphs for rectangular dualisation (IC floorplanning)
Rectangular dualisation is used to generate rectangular topologies in top-down floorplanning of integrated circuits. The author presents an efficient algorithm that transforms an arbitrary graph, representing a custom integrated circuit into one suitable for rectangular dualisation. The algorithm uses efficient techniques in graph processing, such as planar embedding, and introduces a novel procedure to transform a tree of biconnected subgraphs into a block neighborhood graph that is a path.<>
