Your comments are about EDA tools are not totally correct. There are several
EMI tools that simulate emmisions. These are not expert systems but rather
simulation tools. Given that the problem set can be simplified several tools
can do a good job. The problem is really one of user expectation. If your
intention is to build a computer take it to the lab and expect simulation to
match measurement then your expectations are not in line with the tools.
If you want to better understand EMI, the causes, fixes and general trends
then you may benefit from such an EMI simulation tool. An expert system
is built in intelligent rules that may help you avoid common EMI problems
during design. One can use expert systems to help the EMI issue. However
it offers very little or no insight as to the root causes and effect.
There is a wide range of EMI simulation tools. Some only can handle
mode radiation. Some do handle common mode radiation. However the compute
times can become very long and tedious if the problem set is not simplified.
tools of this nature can be also very expensive. Here is a list although not
of EMI simulation tool vendors:
Quad, Quantic Labs, Encases, Applied Simulation Technology, Ansoft
