摘要
为了适应超大规模集成电路自动版图设计的需要，本文提出以改进的群法为基础的宏单元门阵列布局方法．它通过同时考虑单元尺寸及单元连接度进行结群，并结合广义力向量松弛法，具有速度快，迭代改善效果明显等特点．本文最后给出实验例子，验证了算法的有效性．
The growing complexity of integrated circuits poses new challenges to the existing layout design tools. This paper presents a modified clustering approach for macrocell gate array placement. Both connectivities and sizes of cells are taken into account in the clustering process.When combined with Force-Directed-Relaxation method,the algorithm generates promising results and takes a short computation time. Examples are also given to demonstrate the effectiveness of the algorithm.
