Analyzing Power Distribution Networks (PDN)

When to Use

• Analyzing DC voltage and current distribution on PCB power rails
• Checking design rules (max current density, voltage margins, via current limits)
• Discovering and listing power nets on an imported PCB layout
• Assigning source/load/sense topology for PDN analysis
• Running batch analysis across multiple power rails on a board
• Inferring nominal voltage from standard PCB net naming conventions

When NOT to Use

• Importing PCB layouts (Gerber, ODB++, Allegro) — use matlab-read-pcb-layout
• Analyzing S-parameters, fields, or EM performance — use matlab-analyze-em
• Analyzing crosstalk between signal traces — use matlab-design-pcb-txline
• Defining dielectric or conductor materials — use matlab-manage-pcb-material
• Modeling via structures — use matlab-model-via
