Agentic AI & Sigasi Visual HDL

AI coding assistants can generate HDL code faster than ever… but how do you make sure the generated code is actually correct, consistent, and maintainable?

In this screencast, we demonstrate how Cursor and Sigasi Visual HDL work together to create a complete UART design using AI-assisted development with deterministic validation and analysis.

Starting from an empty project, we use an AI agent to generate a UART receiver state machine, a UART transmitter, and finally the UART top-level integration. Along the way, Sigasi Visual HDL continuously analyzes the generated HDL code in real time and provides immediate feedback on correctness, coding guidelines, reset styles, and state machine structure.

You will see how Sigasi Visual HDL helps engineers:

• Validate AI-generated HDL code instantly
• Enforce naming conventions and linting rules
• Guide AI agents using project-specific rules
• Automatically generate fix prompts from linting violations
• Visualize state machine behavior and structure
• Stay in control while accelerating development with AI

Instead of manually reviewing every line of generated HDL (and even worse pushing easy to chatch errors to verification) design engineers can rely on Sigasi’s semantic understanding and deterministic analysis to catch issues immediately and maintain confidence in the generated design.

Built for engineers and agents

Whether code is handwritten or AI-generated, Sigasi helps teams move faster without sacrificing quality or maintainability.
