At CadenceLIVE Silicon Valley 2026 , Cadence Design Systems closed the loop on what is arguably the most ambitious bet in electronic design automation today: an autonomous, end-to-end chip design flow built on AI Super Agents.
The company introduced two new agents — ViraStack for analog design and verification, and InnoStack for digital implementation and signoff — joining the previously launched ChipStack Super Agent for digital RTL design and verification.
With all three in place, Cadence now claims full agentic coverage from specification to signoff. To stitch them together, Cadence also unveiled AgentStack , a unified "head agent" that orchestrates the three Super Agents through a common terminal interface, enabling knowledge and skill sharing across domains.
AgentStack is extensible beyond chip design into 3D-IC, system-level design, and analysis — effectively positioning itself as the control plane for the next decade of Cadence's platform.
This is a substantial step-change from the "AI copilot" era most EDA vendors were still operating in six months ago, and a validation of the broader agentic AI wave sweeping enterprise infrastructure .
Why the timing matters The semiconductor industry has been talking about a "design productivity gap" for years — transistor counts scaling exponentially while design teams scale linearly, and an acute shortage of senior engineers to close the gap.
Paul Cunningham, Cadence's VP and GM of R&D, put it bluntly when ChipStack was first announced earlier this year: customers are staring down a senior-engineer deficit they cannot hire their way out of. Agentic AI has emerged as the industry's answer.
Synopsys has outlined its own vision of an "AgentEngineer" workforce — digital implementation agents, verification agents, analog agents — that customers can lease or buy within the next 12 to 24 months.
