Electromagnetic Interference (EMI) issues are signal integrity issues in disguise.
I see EMC tests as the final exam for your board design.
If the signal integrity aspect is well taken care of, your chance of failing EMC tests is super low.
Why is that?
Because the energy designated for the signal is then efficiently channeled in your circuits, and is used for either information or power, as meant by design.
If these aspects of the design are not well taken care of, then the energy meant for the signals (or power) is wasted in the form of electromagnetic interference and your design suddenly fails the tests, and you can't seem to figure out why.
Learning the hard way, is definitely the most expensive and less efficient way.
Don’t do like me, avoid this simple issue by understanding why this happens before it’s too late.
