Questa One is the Siemens EDA smart verification solution powered by AI, purpose-built to address productivity gaps caused by increasing design complexities of 3DIC and chiplet-based architectures. It accelerates verification through faster engines, automates workflows powered by AI, and reduces verification workloads to achieve improved coverage. Questa One improves overall performance and productivity through, faster engines, faster engineers and fewer workloads.

What is the significance of "One" in Questa One?

The word “one” is about integrating flows, combining engines and unifying applications to provide productivity gains to the end user. For example, AI converts user intent into one automated workflow for total productivity.

What does Questa One deliver?

Questa One synergistically integrates the power of tools, technologies and products by offering over one dozen new products and more than 17 generative, analytic, and prescriptive AI-based capabilities across simulation and debug, design creation, static, formal and verification intellectual property (IP).

As an early influencer on Siemens Questa One Smart Verification Solution, MediaTek has already been able to increase our engineers' productivity across the entire verification process utilizing both formal verification and simulation technologies. Questa One Property Assist utilizes generative AI to save us weeks of engineering time, and Questa One Regression Navigator predicts which simulation tests are most likely to fail, runs them first, and saves days of regression and debugging time.

Chienlin Huang, Senior Technical Manager, MediaTek

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. 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

Tim Costa, General Manager of Industrial and Comp, Nvidia

The productivity gains delivered by the Questa One Agentic Toolkit were both immediate and significant, 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 toolkit not only bridged the knowledge gap but fundamentally accelerated our operational processes

Akshay Aggarwal, Senior Director of Engineering, Mediatek

Combining AI and verification, Questa One enabled our team to quickly adopt full Formal Property Verification and auto-fix issues. With the Agentic Toolkit, we leverage these capabilities at the optimal point in our development flow.
