Beta — Free to evaluate on your schematics

Stop hand-typing failure modes into Excel rows

Stop formatting spreadsheets. Start engineering reliability.

EXITON parses your KiCad netlist, infers failure modes per pin, and outputs an AIAG & VDA compliant DFMEA draft. Entirely on your machine.

Built for: ECU hardware engineers | DFMEA owners | Teams stuck in Excel workflows

Your DFMEA workflow, before and after

What eats your week today
  • 01Manually trace netlist connections across pages
  • 02Copy-paste "Open / Short / Drift" for every pin
  • 03Guess end-effects without signal path context
  • 04Format and merge cells in a 200-row spreadsheet
  • 05Redo half of it after DR feedback
What EXITON handles
  • 01Parses .kicad_sch and builds connection graph
  • 02Assigns roles: Power / Signal / Protection per component
  • 03Infers failure modes from 15-category database
  • 04Chains local effects → end effects with evidence
  • 05Exports AIAG & VDA formatted Excel, ready for review

KiCad to DFMEA in 60 seconds

Import → Analyze → Review → Export. No cloud, no signup.

The real problem
  • ✕Days of data entry before any risk discussion starts
  • ✕No automated path from netlist to failure effects
  • ✕Cloud tools banned — schematics are IP
  • ✕Engineer time wasted on formatting, not engineering
With EXITON
  • ✓Baseline draft in minutes — start reviewing immediately
  • ✓Pin-level connection analysis to end-effect chains
  • ✓100% offline — your design data never leaves your machine
  • ✓Engineers focus on risk mitigation, not spreadsheet labor

What it actually does

No magic. Just automated grunt work so you can focus on real engineering.

📈

Parses netlist and builds connection graph

Reads .kicad_sch natively. Maps every pin connection into Power, Signal, and Protection path graphs for systematic analysis.

🤖

Failure modes from database, not hallucination

15 component categories (resistor, MLCC, electrolytic, MOSFET, IC, connector...). Failure modes are selected from a curated database — not generated from scratch.

📋

S/O/D scoring with confidence and rationale

Each rating comes with High/Medium/Low confidence and a one-line reason. You know exactly where to focus your review.

📚

Effect chains: local → end-effect with evidence

Every DFMEA row records its source: BOM, Schematic, DB, or User. Full traceability for design review.

🔒

100% local processing — your IP stays yours

No cloud calls, no API keys, no external dependencies. Everything runs on your machine. Passes even the strictest infosec policy.

📄

AIAG & VDA 1st Ed. format, not a custom template

Proper AP evaluation table (not simplified rules). Structure analysis, function analysis, failure analysis — all in the standard format.

Coming next

LLM integration and more — on the roadmap, not in the beta.

LLM-assisted failure mode analysis

Use a local LLM (Ollama) or cloud API to rank, explain, and generate failure mode descriptions. Opt-in, not required.

FTA visualization

Fault Tree Analysis diagrams generated from DFMEA data, rendered as Mermaid → SVG.

Human-in-the-loop review UI

Three-stage guided review: component roles → structure/function/failure → S/O/D scoring. Edit directly in the app.

What the output looks like

Structure

AIAG & VDA worksheet with all 7 steps filled

Per component

Failure modes ranked by relevance to circuit role

Effect chains

Local effect → Next higher level → End effect

S / O / D

Initial scores with confidence level and reasoning

Evidence

Source tag per row: BOM / Schematic / DB / User

Change log

Tool-generated initial values vs. your edits, tracked in hidden sheet

Example DFMEA row

dfmea_output.xlsx — row 14
Component U1 (TPS54302 — Buck Converter)
Role Power path — 5V → 3.3V rail
Failure Output voltage overshoot (SW pin short)
Local fx Output exceeds 3.6V absolute max
End effect MCU damage → system non-functional
S / O / D 9 / 3 / 4 — Confidence: Medium
Source Schematic + rule-based analysis

Initial draft accuracy (based on early testing): ~70–80% of failure modes usable with minor edits.

What you still need to do

This is a draft generator, not a finished deliverable. Your engineering judgment makes it real.

  • •Review failure modes — the DB covers common cases, not your edge cases
  • •Adjust S/O/D scores based on your actual test coverage and field data
  • •Validate end-effects — does the tool's inference match your system architecture?
  • •Run cross-functional review before submission
Free beta — no signup, no cloud

Try it on your own schematic

See what EXITON infers from your netlist. If the failure modes don't make sense, tell us — that's how we get better.

Takes ~2–3 minutes to try on your own schematic.

No signup. No cloud upload. Your .kicad_sch stays on your machine.
