AI-powered hardware verification — generate UVM testbenches, assertions, and RTL from natural language

SigmanticAI

AI-powered hardware verification from the command line.

SigmanticAI generates complete chip verification environments — UVM testbenches, SystemVerilog assertions, coverage models, and RTL — from natural language descriptions. Just describe what you need and the AI builds, compiles, and iterates until your design works.

Installation

pip install sigmanticai

Requires Python 3.10+. Verilator is included automatically.

sigmanticai: command not found? Your Python scripts directory may not be on PATH. Try python3 -m sigmanticai as a workaround, or add the path shown in pip's install output to your shell profile:

• macOS/Linux: export PATH="$HOME/.local/bin:$PATH" (add to ~/.zshrc or ~/.bashrc)
• Windows: Add %APPDATA%\Python\PythonXX\Scripts to your system PATH

Quick Start

# Sign in (opens browser)
sigmanticai login

# Interactive mode — chat with the AI agent
sigmanticai

# One-shot generation
sigmanticai generate "Build a UVM testbench for a 32-bit AXI4 FIFO"

What It Does

• Generate verification environments — UVM testbenches, scoreboards, coverage, and assertions from a single prompt
• Design RTL modules — counters, FIFOs, arbiters, interfaces, and more
• Edit existing code — point the agent at your codebase and ask for changes
• Run compilation & simulation — Verilator (bundled), Questa, VCS, Xcelium, and other EDA tools
• Iterative debugging — the agent automatically fixes compilation errors and re-runs until tests pass
• Multi-vendor EDA support — configure your toolchain once, the agent uses the right commands everywhere

Interactive Commands

Inside the REPL:

Command	Description
/tool	Configure EDA tools (simulator, lint, coverage, formal)
/tool reset	Reset tools to defaults (Verilator)
/tool preset <vendor>	Apply vendor preset (synopsys, cadence, siemens, open_source)
/upload <path>	Upload a file or directory for the agent to use
/help	Show available commands
exit / quit / q	End session

EDA Tool Support

SigmanticAI supports multiple EDA vendors out of the box:

Category	Supported Tools
Lint	Verilator, Synopsys SpyGlass, Cadence HAL, Siemens Questa Lint
Simulator	Verilator, Synopsys VCS, Cadence Xcelium, Siemens Questa, AMD XSIM
Coverage	Synopsys VCS Coverage, Cadence IMC, Siemens Questa Coverage
Formal	Synopsys VC Formal, Cadence JasperGold, Siemens Questa Formal

Configure your toolchain with /tool — the agent automatically uses the correct commands, flags, and error patterns for your tools.
