What visualization formats does it use?

It generates diagrams using Mermaid syntax, which can be rendered directly in GitHub, VS Code, and other documentation tools for hierarchies and state machines.

How does it handle very large RTL files?

For files exceeding 80k tokens, the skill employs a Grep-first strategy to extract structure before using chunked reading, preventing context window overflows.

Why does it use multiple subagents?

Using parallel subagents allows the skill to process large codebases much faster while maintaining high analysis accuracy by distributing files across specialized AI workers.

What is Gateflow Architect?

Gateflow Architect is a Claude Code skill designed to automate the mapping, documentation, and architectural analysis of SystemVerilog hardware projects.

Does it support incremental documentation updates?

Yes, by checking the last scan commit against the current HEAD, it identifies changed files and only updates the relevant parts of the codebase map.

Maps and documents SystemVerilog codebases using parallel AI subagents to accelerate RTL project onboarding and architectural analysis.

Gateflow Architect is a specialized professional tool for hardware engineers that automates the complex task of documenting SystemVerilog projects. By orchestrating multiple parallel Sonnet subagents, it deep-scans RTL repositories to generate comprehensive architectural maps including module hierarchies, signal flows, clock domain analysis, and FSM diagrams. Whether you are onboarding to a legacy codebase or preparing for a design review, this skill provides a structured, AI-generated index of your entire hardware design, ensuring that documentation stays in sync with the actual RTL implementation.
