how to design the pcb (printed circuit board) with out affecting EMI interference while it kept near the more noisy place?
what are the steps that I want to design EMI filter as PCB track?
it's in place of industrial purpose.
run the signal with respective planes(i.e. particular signal return path)
use ferrite beads
By adding noise filtering circuit at entering signals (at connectors)
Run shield plane edeges on board
dont run sensitive singals which are clock realted near to power regulator or DC DC converter cirucits

Yes there is software, but it is expensive, learn the basics first, Henry Ott is the main man for EMC design issues and solutions.
