Jia gongxian Why do not you ask your colleague:) Please have a walk of about 20 meter. There is a paper about this kind of topic. The power plane is considered as signal. However, the critical interference is not on the trace, but on the vias. We have this kind of netlist to analyze it. The model has been verified. I hope it will be helpful.
