Cadence Unveils Autonomous AI Engineer for Chip Design Powered by NVIDIA Technologies
Cadence Design Systems has introduced a new autonomous AI engineering platform for semiconductor development at Computex 2026, describing it as the industry’s first Level-5 agentic AI system capable of independently handling chip design and verification tasks.
Built on the company’s ChipStack AI Super Agent platform and powered by NVIDIA technologies, the system is designed to automate some of the most complex stages of semiconductor verification and development.
According to Cadence, the platform incorporates NVIDIA Nemotron models and operates within the OpenShell runtime environment, a secure sandbox created to support autonomous AI agents while safeguarding sensitive design information. The company said the setup enables chipmakers to conduct advanced simulations and automated verification processes without exposing proprietary data.
Paul Cunningham, Senior Vice President and General Manager of Cadence’s System Verification Group, said the company sees AI as a way to help engineers tackle increasingly sophisticated silicon projects more efficiently. He noted that the latest advancement moves beyond AI-assisted workflows toward virtual AI engineers capable of carrying out substantial design and verification work on their own.
Cadence claims the platform can accelerate RTL validation by more than 40 times and shorten verification cycles from approximately five weeks to less than a single day.
The Level-5 autonomous framework is designed to manage a wide range of semiconductor development activities, including interpreting specifications, generating RTL code, creating verification plans, running simulations, performing formal analysis, debugging issues, and guiding designs toward final convergence. Human engineers remain able to oversee and direct the process whenever needed.
The system can also work alongside collaborative development tools such as Codex and Claude Code. Rather than depending on detailed step-by-step instructions, the AI evaluates intermediate outcomes, determines appropriate next actions, and continues iterating until objectives are achieved.
Cadence strengthened its AI portfolio through the acquisition of ChipStack in November 2025 and launched the platform’s first commercial offering in February 2026. The company later expanded the technology into a broader suite of AI-powered engineering tools, including ViraStack AI Super Agent for analog design and InnoStack AI Super Agent for digital implementation and signoff.
Cadence said early-access customers will be able to test the new Level-5 autonomous features of the ChipStack AI Super Agent and the AgentStack orchestration framework during the second half of 2026.
