我在innovus userguide中看到postroute阶段check timing时的一条note,“Is the routing topology similar between postCTS and postRoute wires?Compare the same paths between postCTS and postRoute databases and for large differences in loads",
请教一下大佬们,这句话该怎么理解?是说postCTS和postRoute的绕线模式有什么共同和区别么?还是什么?postCTS不就是优化时钟树吗?postroute不就是优化绕线结果吗?这两个有什么共同吗?还是说优化mode的共同点?请大佬指教。
