State Machine Design

Formal definition of your firmware's state machine — states, transitions, guards, actions, and error recovery paths visualized with state diagrams.

Why It Matters

Embedded systems are inherently state-driven. A formal state machine document prevents undefined behavior, makes testing exhaustive, and gives AI tools precise behavioral specifications.

What's Included

State diagram (Mermaid)
State descriptions
Transition table
Guard conditions
Entry/exit actions
Error states and recovery

How It's Generated

1

AI Research

Gemini with Google Search Grounding researches current SDK documentation, API references, and best practices for your specific hardware platform.

2

Document Generation

GPT-5.1 generates a comprehensive State Machine using the research context, tailored to your project requirements and hardware.

3

Review & Edit

Review the generated document, make edits directly, or use AI refinement to adjust specific sections with custom instructions.

4

Export & Use

Download as part of your project bundle. The document integrates with all other generated docs and code scaffolds.

Other Document Types

PRD

Comprehensive document defining what your firmware product needs to do — functional requirements, non-functional requirements, power budgets, user stories, and acceptance criteria.
