SOC encounter Power pad problem

[red_0220]

Hi all,
I'm using umc90 to do P&R with soc encounter tool.
I only finish floorplan at present and plan to make powerplan now.
A problem will happen to connect power pad (Route > Special Route …) after create power-ring (Power > Power Planning > Add Rings …) .
The problem show on terminal:

----------------------------------------

How can I solve it?

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