1. 先查有没有PORT VDD,VSS.
icc_shell> get_ports -all VDD
icc_shell> get_ports -all VSS
2. 如果没有：
create_port VDD -dir inout
create_port VSS -dir inout
connect_net [get_nets -all VDD] [get_ports -all VDD]
connect_net [get_nets -all VSS] [get_ports -all VSS]

请问一下版主，我的VDD,GND的port也跑到左下角，应该就是unplaced的状态了，然后我用您说的命令却说找不着，但是版图上有port的说，网表上面也有。
icc_shell> set_port_location -coordinate {792.508 -0.500} -layer_name M1 -append {VDD}
Warning: Can't find port 'VDD' in design 'design_top'. (UID-95)
Error: Value for list 'port_name' must have 1 elements. (CMD-036)
0

icc_shell> get_ports -all VDD
{VDD}
