Siemens announced the Questa One Agentic Toolkit, which brings domain-scoped agentic AI workflows to its Questa?? One smart verification software portfolio to accelerate creation, verification planning, execution, debugging and closure to achieve trusted RTL sign-off faster while transforming how engineers approach integrated circuit (IC) design and verification tasks. The verification productivity gap continues to widen as design complexity explodes with 3D ICs, chiplet-based architectures and software-defined systems. The Questa One Agentic Tool kit transforms verification and design from isolated tool interactions into intelligent, domain-scoped multi-step, framework-agnostic workflows powered by agentic AI - autonomous systems operating within the verification domain under customer-defined governance boundaries that can reason, plan and execute complex tasks while maintaining configurable human oversight at critical decision points directly within engineers' existing environments.
Working with Fuse EDA AI system and beyond The Questa One Agentic toolkit works seamlessly with the Fuse?? EDA AI system, Siemens' agentic and generative framework for electronic design automation, providing customers who want a fully integrated Siemens experience with optimized performance and deep integration. Siemens uniquely combines verification engine expertise with deep AI integration and customer choice through three differentiating pillars: Engine-native intelligence: Siemens creates both the Questa One tools and the model context protocols (MCPs) that expose them to agentic frameworks.
These workflows, built leveraging NVIDIA Llama Nemotron and NVIDIA NIM, understand verification state in real time and maintain comprehensive awareness and contextual intelligence relationships between designs, testbenches, test plans and specifications. This provides customers with autonomous goal decomposition, adaptive cross-run strategies and persistent expertise building. Coding application and platform agnostic: The solution works with main-stream AI coding applications - including GitHub Copilot, Claude Code, Cursor, Cline and Siemens' own Fuse - and can be used in CLI mode or IDEs (e.g. VS-Code).
While optimized as Fuse-preferred for customers who want a fully integrated experience based on Siemens' toolset, these workflows remain completely agnostic, adapting to customer workflows rather than forcing adaptation. Configuration fine-tuning suggestions are made based on results. This empowers designers to achieve the cleanest asynchronous designs after reviewing the results and enabling automated AI-powered design fixes or waivers.
The Verification Planning Agent analyzes design specifications and automatically generates comprehensive verification plans. These agents leverage the toolkit's MCPs to work directly with Questa One Verification IQ, Questa One SFV, Questa One Sim and other tools, backed by curated prompt libraries developed by domain experts. Partner and customer experiences with Questa One Agentic AI: Early adopters are already seeing significant productivity improvements: "The increasing complexity of modern chip design and verification requires a new generation of intelligent, agentic workflows that can reason through intricate tasks while maintaining the highest levels of precision," said Tim Costa, general manager of Industrial and Computational Engineering, NVIDIA NVIDIA.
