FPGA Docu draw technical diagram

The problem

Describing technical architecture or circuit layouts in text is easy, but generating precise, production-ready image files usually requires manual drawing tools or fighting with fickle CLI syntax. Developers often end up with broken DOT files or schematics that fail to render correctly in their CI/CD or documentation pipeline.

What it does

• Generates Graphviz .dot source for functional block diagrams and patent-style figures with reference numerals.
• Creates Python-based SchemDraw scripts for component-level electrical schematics including transistors, gates, and passive elements.
• Executes a local validation runner to render source code into SVG or PNG files immediately.
• Ensures zero-error delivery by catching syntax and engine failures before the file is finalized.
• Supports grouped sections, orthogonal routing, and labeled ports for complex signal flow.

Frameworks & tools

Graphviz (DOT), SchemDraw, Python, Matplotlib.

Why this beats prompting it yourself

Generic LLM prompts often hallucinate Graphviz attributes or use deprecated SchemDraw syntax that won't compile. This skill uses a strict "render-first" workflow that forces the agent to fix its own code until the output file is valid and non-empty.

Use cases

• Drafting patent-ready functional diagrams with dashed clusters and reference numbers.
• Visualizing electrical circuits directly from a component list or netlist description.
• Automating SVG diagram generation for technical documentation and READMEs.
• Mapping complex signal flows between software modules or hardware blocks.

Known limitations

Requires Graphviz and the SchemDraw Python package installed on the host system to perform the actual rendering. It is not intended for UI mockups or artistic illustrations.
