13 EMI Function Checks Developed by NEC
(1) Trace length (2) Number of via-holes (3) Traces
crossing over GV planes
(4) Discontinuities of return current path (5)
Traces near plane edges
(6) Estimation of radiated electromagnetic field
Note: Differential mode radiation
+ common mode radiation
(7) SG traces
(8) Distance between grounding vias of SG traces (9)
Grounding vias along ground-plane edge
(10) Filters on a trace connected to a connector (11)
Decoupling capacitor
(12) Differential Pair Check
(13) Crosstalk
