摘要

如果只考虑路由的长度，可能会给以后的路由带来很多麻烦。因此可达性是衡量布局效果的重要指标。本文提出了基于网络分布的可达性优化算法，包括基于网络分布的蜂窝膨胀算法、膨胀率调整算法和网络替换算法。与正常的细胞膨胀相比，我们的放置器对全球网络造成的拥堵更有效，更健壮。在ICCAD 2012[3]基准测试中，我们的放砂机比其他放砂机获得了更好的解决方案。

Net-distribution-based Routability Optimization In Global Placement

The placement only considering the wirelength may cause a lot of troubles in routing later. So routability is an important measure of placement results. In this paper, we propose algorithms for routability optimization including net-distribution-based cell inflation, inflation ratio adjustment and net replacement. Compared with normal cell inflation, our placer are more effective on the congestion caused by global nets and more robust. On ICCAD 2012 [3] benchmarks, our placer obtains better solutions than other placers.
