Dear Hocheol
I agree with your view. Now, the EMC expert system could only check some simple
rules, such as the fanout of decoupling capacitor, the return path of clock
net. It is a rule checker indeed. Have you think about inserting simulation
into the EMC expert system? It is glad to talk about this topic with you.
Best Regards
