Siemens Launches AI-Powered Questa One Agentic Toolkit to Improve Semiconductor Verification Productivity

The Questa One Agentic Toolkit brings domain-scoped agentic AI workflows to its Questa™ One smart verification software portfolio

(IN BRIEF) Siemens Digital Industries Software has launched the Questa One Agentic Toolkit, an AI-driven verification solution designed to accelerate integrated circuit development and RTL sign-off through domain-specific agentic workflows. The toolkit integrates with Siemens’ Fuse EDA AI system while remaining compatible with other AI platforms, allowing teams to automate code generation, verification planning, debugging, and design analysis. Built using advanced AI models and integrated with Siemens verification tools, the system helps engineers manage increasing design complexity and improve productivity. The solution is currently available through an early access program and represents a major step toward AI-driven semiconductor design workflows.

(PRESS RELEASE) NUREMBERG, 27-Feb-2026 — /EuropaWire/ — Siemens Digital Industries Software has introduced the Questa One Agentic Toolkit, a new addition to its Questa One smart verification portfolio designed to accelerate integrated circuit (IC) design and verification through domain-specific agentic artificial intelligence workflows. The toolkit enables engineers to automate and streamline complex verification tasks, helping achieve faster and more reliable register-transfer level (RTL) sign-off while maintaining structured human oversight.

The new solution addresses the growing productivity challenges in chip design verification as system complexity increases with technologies such as 3D integrated circuits, chiplet architectures, and software-defined systems. Instead of relying on isolated tools, the Questa One Agentic Toolkit introduces multi-step AI-driven workflows that can reason, plan, and execute verification tasks within defined governance boundaries while allowing engineers to intervene at key decision points.

The toolkit is designed to integrate closely with Siemens’ Fuse EDA AI system, an agentic and generative framework for electronic design automation. This integration provides enhanced performance and deeper functionality for customers using Siemens’ ecosystem. At the same time, the framework-agnostic architecture allows the toolkit to operate alongside other AI platforms, preserving existing investments and enabling consistent workflows across different environments.

The agentic workflows are designed to operate autonomously within verification processes while building persistent knowledge across multiple runs. The system provides automated goal decomposition, adaptive strategies, and context-aware analysis of relationships between design specifications, testbenches, and verification plans. The solution uses technologies including NVIDIA Llama Nemotron reasoning models and NVIDIA NIM services to support AI-driven verification capabilities.

Several specialized AI agents are included in the initial release. The RTL Code Agent generates synthesizable RTL code from natural-language descriptions and identifies coding issues while suggesting corrections aligned with industry standards. The Lint Agent analyzes RTL code for errors and style violations and can recommend automated fixes or waivers. The Clock Domain Crossing Agent configures and executes verification of asynchronous design elements while providing optimization suggestions.

Additional tools include a Verification Planning Agent that analyzes design specifications and automatically generates structured verification plans, and a Debug Agent that correlates waveforms, logs, coverage data, and assertions to accelerate root-cause analysis. These agents operate through model context protocols that connect directly with Questa One tools such as Verification IQ, SFV and Sim, as well as other components of Siemens’ verification ecosystem including Tessent software and the Veloce CS hardware-assisted verification platform.

The toolkit is compatible with a wide range of development environments and coding tools, including GitHub Copilot, Claude Code, Cursor and Cline, and can be used through command-line interfaces or integrated development environments such as Visual Studio Code. This flexibility allows teams to incorporate agentic AI into existing workflows without significant disruption.

Early adopters have reported substantial productivity gains, with engineering teams able to complete tasks in hours that previously required days and rapidly adopt new verification workflows. The solution is currently available through an early access program.

The introduction of the Questa One Agentic Toolkit reflects Siemens’ broader strategy to integrate artificial intelligence into electronic design automation, enabling more efficient development of increasingly complex semiconductor systems.
