What project files does gf-viz require to function?

It requires a generated codebase map located in the .gateflow/map/ directory, which is typically created by first running the /gf-map command.

Can it help identify linting and design warnings?

Yes, the Overview Dashboard and Module Detail Cards integrate health checks, lint status, and connectivity warnings to help you spot design flaws quickly.

Is gf-viz specific to SystemVerilog?

While optimized for the GateFlow ecosystem which targets SystemVerilog, it focuses on providing structural and behavioral insights for RTL-based hardware design.

Can I view FSM diagrams directly in my terminal?

Yes, gf-viz renders interactive FSM state machines using ASCII/Unicode boxes, arrows, and transition tables for a clear visual representation of logic.

Does it support natural language queries for navigation?

Yes, you can use free-form queries like 'show uart_tx' or 'trace the data path' to jump directly to specific modules or analysis views.

分析と監視

Visualizes SystemVerilog module hierarchies, FSM diagrams, and RTL codebase maps using interactive terminal-based ASCII art.

GateFlow RTL Visualizer (gf-viz) is a specialized Claude Code skill designed for hardware engineers to navigate and understand complex SystemVerilog projects. It transforms static codebase maps into interactive, terminal-based visualizations, allowing users to explore nested module hierarchies, inspect Finite State Machine (FSM) diagrams, and analyze module-level details such as ports, parameters, and signal bindings. By providing a clear, navigable visual representation of RTL architecture, it simplifies the process of architectural review, debugging, and signal tracing without ever leaving the command-line environment.
