## What is Voltcanopy?

Voltcanopy is a system-level power architecture workbench for embedded engineers, electronics designers, robotics teams, students, and technical reviewers.

Build a cascaded source and rail tree, attach typical and peak loads, and preserve current limit, efficiency, dropout, thermal resistance, maximum junction temperature, startup delay, and dependency intent. Voltcanopy recursively rolls downstream demand through every conversion stage so source current, rail current, output power, conversion loss, headroom, and first-pass junction rise remain visible.

KEY FEATURES
- Cascaded source, regulator, and rail model
- Typical, peak, duty, and transient load records
- Recursive downstream power accounting
- Current-limit and source-budget screens
- Input, output, dropout, and voltage-headroom checks
- Efficiency loss and theta-JA thermal screen
- Startup order and dependency-cycle detection
- Local PDF and JSON architecture export
- Complete editable edge-controller sample
- 340 original offline power-design plates
- No account, ads, analytics, tracking, IAP, or subscription

Voltcanopy is a first-pass architecture and documentation tool. Confirm regulator limits, transient behavior, component derating, sequencing, layout, thermal paths, protection, fault response, and measurements against current datasheets and qualified engineering review.
