同时非均匀分段和非统一缓冲器插入算法
Simultaneous non-uniform wire segmenting and buffer insertion
摘要
Abstract
The paper proposes a non-uniform wire segmenting and buffer insertion algorithm, which can effectively solve the problem of driving long wires with heavy load. The algorithm considers the resistance effect and the capacitance effect of the interconnects, adopts a geometrically progressive buffer chain to drive the large load, and computes the delay using the adjustable wire segments at the same time. It can yield the accurate prediction of the delay of buffer insertaion while considering the impact of blockages on the layout. The experimental results show that this algorithm can optimally solve the large-load-driving problem and can be efficiently adopted in the floorplan and placement stage which can guarantee timing closure and design convergence while saving the routing resources.关键词
