###LAB10-2 Running the Early Global Router 本章节学习目标是通过工具的前期global router 引擎来分析发现潜在绕线问题 GUI操作步骤:Route---Early Global Route (等效命令是earlyGlobalRoute) 上图中选择的Route layer这步界面操作等效于使用下面的命令。 setRouteMode -earlyGlobalMaxRouteLayer 3 -earlyGlobalMin...
在Place阶段进行Gobal Route/Early Global Route可以很好地预估后续Route的情况,但是工具在优化计算时序时对电阻电容参数(RC Factor)的默认值为1,这明显是不合理的,所以Innovus可提供generateRCFactor命令对RC Factor进行提取和比较,用户以此来更新viewDefination文件中PreRoute和PostRoute阶段的RC Factor。 RC Factor通过比...
global placement完成后,工具会进行refinePlace。此时,可以看到instance的平均移动距离以及最大移动距离。一般不超过10个row都不算异常,如下图所示,平均距离为0.27um,最大距离为7.1um。 还可以查看earlyGlobalRoute之后的congestion情况,下图显示了horizontal和vertical的congestion情况,一般overflow小于2%表示后续绕线没有问题...
