5. After such, to apply the rules, go to Electrical > Net > Routing > Return Path, choose the net you want to apply your
ECSet to, and that's it.
Impact on the Board:
f
Improves overall reliability and performance of the PCB in various electromagnetic environments
f
Ensures compliance with regulatory standards, which is essential for product certification and market entry
f
May influence component placement, routing strategies, and layer stack-up decisions
f
Can lead to the inclusion of additional shielding or filtering components
f
Might require changes in trace routing to minimize crosstalk and emissions
By implementing proper EMC and EMI constraints like return path checking, designers can create PCBs that not only function
well but also meet the stringent electromagnetic compatibility requirements of modern electronic devices.
