PLANO, TX, Mar 2, 2026 – Siemens has added the Questa One Agentic Toolkit to its Questa One smart verification software portfolio. The toolkit introduces domain-scoped agentic AI workflows to integrated circuit design and verification. It supports verification planning, execution, debugging and closure to help engineering teams move toward RTL sign-off efficiently.
Siemens introduced the Questa One Agentic Toolkit to apply domain-scoped agentic AI workflows to verification processes. The toolkit supports multi-step task execution under customer-defined governance controls while keeping engineers involved at critical decision points within existing environments.
“Questa One sets a new standard for smart verification and the Questa One Agentic Toolkit builds on those connected and data-driven principles with agentic AI workflows that empower our customers to achieve trusted design and verification closure with AI acceleration – while maintaining the human expertise and judgment that builds quality and trust,” said Abhi Kolpekwar, senior vice president and general manager, digital verification technologies, Siemens Digital Industries Software. “We own the engines and we understand verification at the deepest level. It isn’t an afterthought or a wrapper; it’s the EDA industry’s most comprehensive verification solution enhanced with intelligent agentic AI workflows that work the way our customers expect and delivers the results they are demanding.”
Working with Fuse EDA AI System and Beyond
Siemens built the Questa One Agentic Toolkit to work with the Fuse EDA AI system, its agentic and generative framework for electronic design automation. When used inside the Fuse environment, the toolkit offers additional functionality tied to that integration.
The architecture remains framework-agnostic, allowing it to interoperate with other agentic platforms and toolchains. Standardized interfaces let the workflows run across different development environments without changing underlying processes.
The Siemens Advantage: Engines, Integration and Openness
These agentic workflows take a different approach from standalone AI tools focused on specific verification tasks. Siemens integrates verification engine capabilities with AI and offers multiple implementation options across three defined areas:
- Engine-native intelligence: Siemens develops both the Questa One tools and the model context protocols (MCPs) that expose them to agentic frameworks. The workflows use NVIDIA Llama Nemotron and NVIDIA NIM and track verification state in real time. They maintain context across designs, testbenches, test plans and specifications. The system supports goal decomposition, cross-run strategy adjustment and expertise building.
- Coding application and platform agnostic: The solution integrates with main-stream AI coding applications – including GitHub Copilot, Claude Code, Cursor, Cline and Siemens’ Fuse. It supports use in CLI mode and IDEs such as VS Code. When used within the Fuse environment, the workflows offer integration with Siemens tools.
- Scalable, connected, data-driven foundation: The workflows operate across Siemens verification tools, including Questa One, Tessent software for DFT and the Veloce CS verification and validation system. The integration enables AI-based functions within design and verification processes.
Intelligent Workflows Across Design and Verification
The Questa One Agentic Toolkit launches with the following agents that explain the potential of agentic AI:
- The RTL Code Agent generates synthesizable RTL code from natural language descriptions and checks for coding violations. It flags any coding violations and recommends corrections based on industry standards for review.
- The Lint Agent configures lint analysis and reviews existing RTL code for design errors and coding style violations. Designers review the results and can apply automated fixes or waivers.
- The CDC Agent configures and runs clock domain crossing verification on a design. It provides configuration adjustment suggestions based on results. Designers review the findings and can apply automated fixes or waivers generated by the AI system.
- The Verification Planning Agent analyzes design specifications and generates verification plans. Engineers review and approve each step, while the AI handles structuring sections, drafts feature descriptions, defines scenarios and checks verification strategies.
- The Debug Agent correlates waveforms, assertions, coverage data and log files during root cause analysis. It flags signal transitions for review, suggests possible failure mechanisms and generates debug scenarios.
These agents use the toolkit’s MCPs to interface with Questa One Verification IQ, Questa One SFV, Questa One Sim and related tools.
Partner and Customer Experiences with Questa One Agentic AI
“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. “By leveraging NVIDIA NIM and Nemotron reasoning models, Siemens is providing engineers with a powerful, AI-driven foundation to accelerate the development of the world’s most advanced electronic systems.”
“The productivity gains delivered by the Questa One Agentic Toolkit were both immediate and significant,” said Akshay Aggarwal, senior director of Engineering, MediaTek. “Our engineers were able to become proficient within hours, despite limited prior exposure to the tool – completing tasks that typically require days, and mastering workflows that would usually take weeks of training. In combination with MediaTek’s existing advanced in-house verification methodology, the Questa One Agentic Toolkit not only bridged the knowledge gap but fundamentally accelerated our operational processes.”
“Combining AI and verification, Questa One enabled our team to quickly adopt full agentic Formal Property Verification, and auto-fix issues with Lint Agent,” said Shalesh Thusoo, founder and chief executive officer, Tsavorite Scalable Intelligence. “With the Agentic Toolkit, we leverage these capabilities and their productivity gains at the optimal point in our development flow.”
