matlab-analyze-pcb-pdn
PDN DC voltage/current analysis, IR drop, design rule checking, and multi-net batch analysis on imported PCB layouts. TRIGGER: user asks about power integrity, PDN analysis, IR drop, voltage distribution, current density, power nets, or design rule checking on a PCB. Invoke BEFORE writing code — the PDN API chain is specialized and non-obvious. SKIP: importing a PCB file (use matlab-read-pcb-layout), EM field/S-parameter extraction (use matlab-analyze-em), material/stackup setup only (use matlab-manage-pcb-material), transmission line design (use matlab-design-pcb-txline).

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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` ## Typical Workflow 1. **Before:** `matlab-read-pcb-layout` — import the PCB layout from Gerber/ODB++/Allegro 2. **This skill:** Run DC analysis, check IR drop, evaluate design rules, batch-analyze nets 3. **After:** Iterate on the physical design in CAD and re-import, or use results to inform stackup changes via `matlab-manage-pcb-material` ## Quick

What does the matlab-analyze-pcb-pdn skill do?
PDN DC voltage/current analysis, IR drop, design rule checking, and multi-net batch analysis on imported PCB layouts. TRIGGER: user asks about power integrity, PDN analysis, IR drop, voltage distribution, current density, power nets, or design rule checking on a PCB. Invoke BEFORE writing code — the PDN API chain is specialized and non-obvious. SKIP: importing a PCB file (use matlab-read-pcb-layout), EM field/S-parameter extraction (use matlab-analyze-em), material/stackup setup only (use matlab-manage-pcb-material), transmission line design (use matlab-design-pcb-txline).
How do I install it?
Run `npx skills add matlab/matlab-agentic-toolkit --skill matlab-analyze-pcb-pdn --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From matlab/matlab-agentic-toolkit, a repository with 868 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
