摘要

线性互连是一种很有前途的缩短导线长度的技术。本文提出了两种实用的启发式八线性斯坦纳树(OSMT)算法。它们都是基于八线性生成图的。边缘替换算法(OST-E)的最坏情况运行时间为0 (nlogn)，性能与批处理贪婪算法相似[9]。另一种是三角收缩(OST-T)，运行时间增加较少，性能更好。在工业和随机测试用例上进行了实验。

Efficient octilinear steiner tree construction based on spanning graphs

0ctilinear interconnect is a promising technique to shorten wire lengths. We present two practical heuristic octilinear Steiner tree (OSMT) algorithms in the paper. They are both based on octilinear spanning graphs. The one by edge substitution (OST-E) has a worst case running time of O(nlogn) and similar performance as the batched greedy algorithm[9]. The other one by triangle contraction (OST-T) has a small increase in running time and better performance. Experiments on both industry and random test cases are conducted.
