APlace是一种高质量、可扩展的分析砂岩。本文描述了我们最近为提高Aplace的速度和可扩展性所做的努力。我们探索了各种线长和密度近似函数。在多层布局过程中，我们使用线长度和密度近似的混合使用来加速布局，并在IBM ISPD04和ISPD05基准上获得了2-2.5倍的全局布局加速比。还简要描述了Aplace框架在电源电压退化感知布局和透镜像差感知定时驱动布局方面的最新应用。
APlace is a high quality, scalable analytical placer. This paper describes our recent efforts to improve APlace for speed and scalability. We explore various wirelength and density approximation functions. We speed up the placer using a hybrid usage of wirelength and density approximaions during he course of multi-level placement, and obtain 2-2.5 imes speedup of global placement on the IBM ISPD04 and ISPD05 benchmarks. Recent applications of the APlace framework to supply voltage degradation-aware placement and lens aberration-aware timing-driven placement are also briefly described.
