en.Wedoany.com Reported - Cadence has announced new capabilities for its ChipStack AI super agent, advancing the platform to Level-5 autonomy. Built on Cadence's electronic design automation (EDA) tools, the agent leverages the NVIDIA Nemotron model and ensures security through the NVIDIA OpenShell runtime environment, enabling customers to run dynamic simulations in automated workflows.
The ChipStack AI super agent operates with high autonomy in chip design and verification workflows, while allowing engineers to review results, guide processes, and collaborate when needed. It integrates into collaborative environments, working alongside tools such as Codex and Claude Code to provide visibility into system activities and decisions. Rather than following step-by-step prompts, the agent evaluates intermediate results, determines next actions, and iterates across tasks including specification understanding, RTL generation, verification planning, formal analysis, simulation, debugging, and design convergence. Engineers can focus more on reviewing results and setting goals, while the system handles more of the workflow.
Cadence connects autonomous agent behavior with its physics-based design and verification engines, ensuring AI-driven operations are grounded in existing computational models and signoff-oriented results. In deployment, the super agent runs within the NVIDIA OpenShell runtime, a sandbox environment for autonomous agents that applies governance controls, protecting intellectual property through policy enforcement, isolation, and managed access to tools, infrastructure, and design data. Cadence combines its design and verification engines with OpenShell security controls as part of the production deployment approach.
According to Cadence, NVIDIA engineers annually use massive computing resources to verify chip designs. With the ChipStack agent leveraging Cadence Xcelium logic simulation and Jasper formal verification, it can run extensive dynamic simulations, accelerating RTL verification by over 40 times and reducing verification cycles that typically take five weeks to less than one day.
This release builds on prior collaboration between Cadence and NVIDIA in agentic AI. After acquiring ChipStack in November 2025, Cadence launched its first product in February 2026, expanded its portfolio at CadenceLIVE in April with the ViraStack AI super agent for custom and analog design, the InnoStack AI super agent for digital implementation and signoff, and the Cadence AgentStack framework for agent workflow orchestration across the design stack. This update pushes these capabilities further toward autonomous operation. Cadence expects the new autonomous capabilities in the ChipStack AI super agent and AgentStack orchestration framework to be available to early adopter customers in the second half of 2026.
