在icc中,通过preroute_instances -primary_routing_layer preferred -preferred_routing_layer high命令,将电源PAD的引脚同core power ring相连接的时候, 遇到一堆的 warning如下: WARNING: Failed to make a connection for the following pin: ((1728.520, 1007.905) (2035.995, 1010.105))(Net: VDD)(wire on layer: M4 [64]) Warning: wire dropped because obstruction,((2036.070 1007.905) (2036.220 1010.105)) (Net: VDD) (Layer: M3 [63]) isblocked by ((1729.930 930.200) (2035.995 2037.060)) (Net: null) (Layer: M3[63]).
