SOC encounter Power pad problem

red_0220

小弟目前练习使用UMC90制成用soc encounter去做P&R
目前只做完floorplan正要做powerplan
建立好power-ring (Power > Power Planning > Add Rings …)
之后连接power pad (Route > Special Route …)会出现以下错误而不能连metal到VCC跟GND

能否提示一下大概是什么问题?
感恩

(Top/Bottom Layer
METAL9 H ,Left/Right Layer
METAL6 V, Width = 8 , Use wire group,interleaving number of bits = 4 ,電源VCC cell type = VCCKGA )

是不是格点问题。。

很奇怪，为什么.lib的cell 需要拉follow pin。
你应该是先拉follow pin 在place，查下你的flow

哎，问题多多啊！！！
