本文采用带冗余通道的双边单元模型,提出了一种有效的LSI自动布局算法.算法中运用“等分接点法”进行单向的布局初始构造,并用多种方式进行布局的迭代优化处理.由于在布局过程中对所有纵向连线的通道分配进行了统一的考虑,提高了设计的整体合理性.本文提出的布局算法和我们提出的“通道区布线的通道损益分析法”可望成为一个有效的布图设计系统的基础. In this paper, an efficient LSI auto-layout algorithm is proposed by using the bilateral cell model with redundant channels. The algorithm uses the “equal-tap method” to construct the initial layout in one direction and iteratively optimizes the layout in various ways. Due to the unified consideration of the channel allocation of all vertical connections in the layout process, the overall rationality of the design is improved.The layout algorithm proposed in this paper and our proposed “channel gain and loss analysis method of channel area routing” is expected to become one An effective layout design system.
