摘要: 该文以多芯片组件布线中的四通孔(V4R)算法为基础,针对其布线结果不均匀、产生多余噪声的缺陷,通过引入PST(Priority Search Tree)和LEA(Left Edge Algorithm)方法,移除过孔或拐角,减小布线层数,减少噪声,以达到总体布线结果优化。计算机模拟结果表明,优化后的算法有效利用了布线空间,在电特性方面使延时和噪声均得到减小。

Abstract: Aiming at the uneven routing results and much noise, this paper presents an improved method for multichip module routing that based on the four-via routing algorithm. By using the PST(Priority Search Tree) and LEA(Left Edge Algorithm) algorithms to restrict routing layers, remove vias or jogs and reduce noise, the result is optimized. The computer simulation results show that routing space is efficiently utilized and the delay and noise are also reduced in the field of electric feature. -
