Siemens Debuts Agentic AI in Questa One

Siemens unveils the Questa One Agentic Toolkit, which brings domain-scoped agentic AI workflows to its Questa One smart verification software portfolio.
 
The Questa One Agentic Toolkit helps advance verification and design from isolated tool interactions into intelligent, domain-scoped multi-step, framework-agnostic workflows powered by agentic AI.

"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," says Abhi Kolpekwar, senior vice president and general manager, Digital Verification Technologies, Siemens Digital Industries Software. 

Working with Fuse EDA AI System

The Questa One Agentic Toolkit works with the Fuse EDA AI system, Siemens’ agentic and generative framework for electronic design automation. It is Fuse-preferred, with enhanced capabilities when used within the Fuse environment. The framework-agnostic architecture protects existing investments and integrates with other agentic platforms.

Siemens combines verification engine expertise with deep AI integration and customer choice through three pillars:

• Engine-native intelligence: Siemens creates 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 awareness and contextual intelligence relationships between designs, testbenches, test plans and specifications. 
• Coding application and platform agnostic: The solution works with mainstream AI coding applications and can be used in CLI mode or IDEs (e.g. VS-Code). While optimized as Fuse-preferred for customers who want an integrated experience based on Siemens’ toolset, these workflows remain agnostic, adapting to customer workflows.
• Scalable, connected, data-driven foundation: By leveraging the connected verification ecosystem, these agentic workflows bring AI-powered capabilities across the design and verification landscape.

Intelligent workflows across design and verification

The Questa One Agentic Toolkit launches with the following intelligent agentsI:

• The RTL Code Agent generates synthesizable RTL code from natural language descriptions while checking for coding violations and suggesting fixes aligned with industry standards.
• The Lint Agent configures lint analysis, reading existing RTL code to check for design errors and coding style violations. Designers then review results and are offered automated AI-powered design fixes or waivers. 
• The CDC Agent optimally configures, then runs clock domain crossing verification on a design.  
• The Verification Planning Agent analyzes design specifications and automatically generates verification plans. Engineers review and approve each step while the AI handles structuring sections.
• The Debug Agent accelerates root cause analysis by correlating waveforms, assertions, coverage data and log files. It identifies suspicious signal transitions, suggests potential failure mechanisms and generates targeted debug scenarios for engineer reviews.

These agents leverage the toolkit's MCPs to work directly with Questa One Verification IQ, Questa One SFV, Questa One Sim and other tools.
