摘要

本文提出了一种适用于一般单元集成电路设计的受时间影响的平面规划器。地板规划师的工作分为两个阶段。在第一阶段,我们将模块限制为刚性,并将平面图限制为切片。平面图的第二阶段允许修改单个模块的长宽比,以进一步减少整体边界框的面积。第一阶段采用遗传算法实现,第二阶段采用基于约束图的方法。并给出了实验结果。

Timing influenced general-cell genetic floorplanner
In this paper we present a timing-influenced floorplanner for general cell IC design. The floorplanner works in two phases. In the first phase we restrict the modules to be rigid and the floorplan to be slicing. The second phase of floorplanner allows modification to the aspect ratios of individual modules to further reduce the area of the overall bounding box. The first phase is implemented using genetic algorithm while in the second phase we adopt a constraint graph based approach. Experimental results are also presented.
