Model high-speed via transitions in MATLAB by defining the viaSingleEnded geometry with correct signal pads, antipads, and ground return vias. This allows you to extract S-parameters and evaluate signal integrity through multi-layer PCB stackups.

Ground return via placement controls return-path inductance in RF PCB designs. Proper GRV placement reduces resonance risk in high-speed links by ensuring adequate return current paths across target frequency bands.

Yes, you can use criticalwavelength and gapratedistance to evaluate ground return via adequacy in multi-layer PCBs. These metrics help assess resonance risk and determine if GRV spacing is sufficient for your target frequency band.

The correct input format for specifying via locations is [x y startLayer stopLayer]. This ensures the viaSingleEnded setup uses proper signal and ground layer conventions for accurate multi-layer transition modeling.

No, this MATLAB via modeling workflow skips general signal integrity, transmission-line design, EM, and PDN workflows. It specifically targets via-focused signal integrity through layer transitions using viaSingleEnded and GRV placement.

PCB via models show incorrect geometry when signal and ground layer conventions are misapplied. Defining the viaSingleEnded geometry with accurate [x y startLayer stopLayer] locations and proper antipads prevents incomplete via transitions.
