Siemens Digital Industries Software announced the Questa One Agentic Toolkit, an addition to its Questa One smart verification software portfolio. The toolkit incorporates domain-scoped agentic AI workflows to accelerate integrated circuit (IC) design and verification tasks, including creation, verification planning, execution, debugging, and closure for register-transfer level (RTL) sign-off.
It addresses the widening verification productivity gap caused by increasing design complexity from 3D ICs, chiplet-based architectures, and software-defined systems.
The solution shifts from isolated tool interactions to intelligent, multi-step, framework-agnostic workflows using agentic AI — autonomous systems that operate within the verification domain under customer-defined governance boundaries. These systems reason, plan, and execute complex tasks with configurable human oversight at key decision points.
The toolkit integrates seamlessly with Siemens’ Fuse EDA AI system, an agentic and generative framework for electronic design automation, offering optimized performance in the Fuse environment while remaining framework-agnostic to preserve existing investments and support other platforms via standardized interfaces.
Siemens highlights three pillars: engine-native intelligence using Model Context Protocols (MCPs) with NVIDIA Llama Nemotron and NVIDIA NIM for real-time verification state awareness, goal decomposition, adaptive strategies, and persistent expertise; coding application and platform agnosticism compatible with tools like GitHub Copilot, Claude Code, Cursor, Cline, and Fuse, in CLI or IDE modes; and a scalable, connected foundation linking Questa One with Tessent for DFT and Veloce CS for hardware-assisted verification.
The initial release includes five agents:
RTL Code Agent: Generates synthesizable RTL from natural language, checks violations, and suggests fixes.
Lint Agent: Configures lint analysis, detects errors and style violations, and offers automated fixes or waivers.
CDC Agent: Configures and runs clock domain crossing verification, provides fine-tuning suggestions, and enables fixes or waivers.
Verification Planning Agent: Analyzes specifications to generate verification plans, with engineer review and approval.
Debug Agent: Correlates waveforms, assertions, coverage, and logs for root cause analysis, suggesting failure mechanisms and debug scenarios.
These agents use MCPs to interact with Questa One tools and curated prompt libraries.
Abhi Kolpekwar, senior vice president and general manager of Digital Verification Technologies at Siemens Digital Industries Software, stated that the toolkit enhances verification with agentic AI while preserving human expertise.
Early adopter feedback includes productivity gains reported by MediaTek, with engineers becoming proficient quickly and completing tasks faster, and Tsavorite Scalable Intelligence noting adoption of agentic formal property verification and auto-fixes.
Tim Costa, general manager of Industrial and Computational Engineering at NVIDIA, commented on the use of NVIDIA NIM and Nemotron models.
The Questa One Agentic Toolkit is available now through an early access program.
