Modeling Vias

When to Use

• Modeling signal vias through multi-layer PCB stackups (viaSingleEnded)
• Configuring pad and antipad geometry per layer
• Placing ground return vias for signal integrity
• Analyzing via S-parameters and identifying barrel resonances
• Evaluating GRV placement with criticalwavelength and gapratedistance

When NOT to Use

• Designing transmission lines or impedance control — use matlab-design-pcb-txline
• Building custom PCB structures from shapes — use matlab-assemble-pcb-layout
• Setting up substrate or conductor materials — use matlab-manage-pcb-material
• Running full-wave EM analysis on non-via structures — use matlab-analyze-em
• PDN analysis on imported boards — use matlab-analyze-pcb-pdn
