定时驱动布局问题的描述与算法

TIMING-DRIVEN PLACEMENTDESCRIPTION AND ALGORITHM

定时驱动布局是减小ＩＣ延时的重要手段。本文通过描述其目标函数与约束条件，给出一种用延时表示弹性系数的力向量算法。它具有速度快、布局目标准确等特点。

Timing-driven placement is an important method to reduce iC delay. By describing its target and constraints, this paper presents a force--directed placement algorithm based on the delays. The algorithm runs fast and can design the high performanceIC.
