Turning Vision into Reality: How Questa One Fulfills the Promise of Smart Verification

The design landscape has evolved dramatically. Exploding complexity, tighter timelines, and a critical engineering talent shortage have turned verification into a bottleneck to innovation. Siemens anticipated this shift in Breaking the bottleneck, where we called for a smarter, more scalable approach to functional verification.²

That vision is no longer theoretical.

With Questa™ One, Siemens delivers on that call with a next-generation smart verification solution engineered for the challenges of modern SoCs, 3D ICs, and software-defined architectures. Questa One reimagines verification as an intelligent, proactive, and adaptive system—one that unifies teams, automates decision-making, and accelerates every step from test creation to coverage closure.

By combining connected workflows, data-driven intelligence, and AI-powered scalability, Questa One turns vision into execution. It delivers not just faster engines, but faster engineers—and fewer workloads.

With over a dozen new products and 17 AI-enhanced capabilities spanning simulation, formal, debug, and verification IP, Questa One redefines what a smart verification system can be. It enables faster engines, faster engineers, and fewer workloads by unifying applications, automating workflows, and simplifying how engineering teams deliver confidence in silicon.

Core Tenets of Questa One

Questa One is built on three foundational pillars—connected, data-driven, and scalable verification—each translated from concept to concrete capability. These tenets echo the framework introduced in Breaking the bottleneck.

The name “One” reflects this unification—bringing together previously siloed engines, flows, and applications into a single, intelligent verification solution that drives total productivity.

These pillars are more than guiding principles—they now manifest as tangible capabilities that reshape how teams approach verification.

Connected verification: Modern verification requires more than isolated tools. Questa One connects engines, flows, and teams into a unified ecosystem that spans simulation, static, formal, and IP-based workflows:

• Unified flows across simulation, formal, and static engines.
• Deep integrations with Tessent™ test solutions and Veloce™ CS hardware-assisted verification for full-system coverage.
• Centralized debug and regression management via Questa Verification IQ.
