【摘要】 由于多芯片组件(MCM)布线中所使用的四通孔(v4R)算法在时钟线网布线中不考虑其无时延偏差的特殊布线要求,会使同步功能失控.针对这一缺陷,对MCM的时钟布线提出了一种新的方法.通过引入MMM(MethodofMeansandMedians)方法,使得自动布线结果中,时钟源点到各作用单元的时延相等,从而改进了v4R算法.更多还原

【Abstract】 Because the four-via routing algorithm does not take the requirement of no timing delay in multi-chip module (MCM) clock routing into consideration, there will be a skew among the clock pins. This paper presented a new method, which combines the Method of Means and Medians and v4R algorithm, to balance the skew of clock net, and thus imoprove the v4R algorithm.更多还原
