AI chip design agents for RTL and verification

Ship verified RTL faster.

SigmanticAI gives semiconductor teams a hardware-native AI platform for high-coverage verification and RTL development, enabling AI agents to understand RTL, edit code, run EDA tools, close coverage, and preserve design context across every iteration.

The orchestration layer for hardware

A hardware-native agent system.

SigmanticAI turns frontier models into a coordinated engineering workflow purpose-built for semiconductor teams.

Deploy Hardware Design Agents

Spin up specialized agents for UVM, SVA, coverage, RAL, RTL, and convergence — orchestrated by a director that plans, delegates, and verifies across your design.

Automate Verification Workflows

Compile → simulate → fix loops run automatically against your real EDA stack until tests pass and coverage closes. The workflow runs itself.

Train Private AI Models

Turn your accumulated RTL and design history into private models that capture your team's engineering knowledge — never shared, never used to train anyone else.

The trajectory

We built the workforce first.
Now we're teaching it to run autonomously.

Most companies start with a narrow tool and try to grow into a platform. We started with the platform — and we're extending it toward fully autonomous specification-to-silicon engineering.

Phase 1 Completed

Agent-Assisted Engineering

  • RTL generation
  • Verification generation
  • Debugging
  • Documentation
Phase 2 Completed

Agent Collaboration

  • Multi-agent design reviews
  • Verification planning
  • Coverage closure
Phase 3 In progress

Specification → RTL

  • Architecture extraction
  • Requirement decomposition
  • RTL generation
Phase 4

Specification → Verified IP

  • End-to-end autonomous execution
Phase 5

Specification → Silicon

  • Timing
  • Physical design
  • Signoff support
The value is in the orchestration layer

A model is a tool.
SigmanticAI is the system that runs it.

General-purpose coding assistants stop at generating text. SigmanticAI is the infrastructure around the model — agent orchestration, real EDA execution, and private design knowledge — that turns it into engineering output.

Brain Cache

A persistent knowledge graph (.sigmanticaicache/) of your spec, ports, architecture, and coverage state. Every agent reasons from the same deep context.

About SigmanticAI

SigmanticAI is the AI operating system for semiconductor engineering. Companies use it to deploy specialized hardware design agents, automate verification workflows, and train private AI models on their own RTL and design history.

Behind a simple conversational interface, a hierarchical multi-agent system orchestrates every concern: UVM testbenches, SVA assertions, coverage models, register abstractions, RTL, Makefiles, and iterative convergence — executing against your real EDA stack. A persistent Brain Cache keeps all agents aligned on your design intent.

Our goal is simple: turn every semiconductor company's accumulated engineering knowledge into an AI engineering workforce. Get started with pip install sigmanticai.
