Summary: Siemens has launched PAVE360 Automotive, a pre-integrated, off-the-shelf digital twin platform designed to tackle the growing complexity of software-defined vehicles. The system enables early, full-vehicle virtual integration across ADAS, automated driving and IVI, allowing software to be developed and validated against realistic hardware representations from day one. By removing the need for OEMs and suppliers to build their own system-level digital twins, PAVE360 can cut development timelines from months to days.
Engineering takeaway: PAVE360 provides a ready-to-use, system-level digital twin that mirrors real vehicle hardware and supports both application and low-level software development. Integration with Arm Zena Compute Subsystems delivers hardware-like simulation speeds, enabling earlier validation and faster iteration. A single shared digital twin reduces integration friction across domains and teams.
Why it matters: As SDV architectures scale in complexity, early system-level validation becomes critical to avoid late integration issues. An off-the-shelf digital twin lowers cost, risk and time-to-market while improving cross-domain collaboration. Strategically, it accelerates the shift from incremental development to a truly software-first vehicle engineering model.
Today, Siemens, a leading industrial technology company, unveiled its PAVE360™ Automotive technology, a new category of digital twin software that is pre-integrated and designed as an off-the-shelf offering to address the escalating complexity of automotive hardware and software integration.
PAVE360 Automotive empowers automotive manufacturers and suppliers to speed the development of software-defined vehicles (SDVs) with early full-system, virtual integration that mirrors real vehicle hardware and accelerates both application and low-level software development for ADAS, AD and IVI. This removes the need for customers to build their own digital twins before testing software and significantly reducing time to market for critical applications – from months to days.
With vehicle hardware and software complexity rising at an unprecedented rate, development teams face mounting pressure to deliver innovation faster and compete with new market entrants while meeting increasingly sophisticated consumer expectations. Traditional development methodologies are no longer sufficient to manage system-level interdependencies between ADAS, AD and IVI functions – a new approach is required.
“The automotive industry is at the forefront of the software-defined everything revolution and Siemens is delivering the digital twin technologies needed to move beyond incremental innovation and embrace a holistic, software-defined approach to product development,” said Tony Hemmelgarn, president and CEO, Siemens Digital Industries Software. “PAVE360 Automotive will empower automotive companies to innovate with confidence, agility and scale, to realize the full potential of the SDVs and set the standard for what’s possible across all industries.”
PAVE360 Automotive: A virtual blueprint for digital twin development PAVE360 Automotive leverages Siemens’ expertise in digital twin technology empowers automakers to:
- Jumpstart vehicle systems development from the earliest phases with ADAS, AD and IVI customizable virtual reference designs
- Unify development, optimize efficiency and increase cloud-based collaboration with a single digital twin for all teams
- Customize and scale by adding software, models and external hardware as needed
- Speed up software development leveraging hardware-like simulation speed of the latest automotive IP, including the new Arm® Zena Compute Subsystem (CSS)
- Validate with real-world feedback by connecting digital twins to physical hardware and testing in real vehicles
System-level digital twins for SDVs using existing technologies can be complex and time consuming to create and validate. To solve this bottleneck, PAVE360 Automotive delivers a fully integrated, system-level digital twin that can be deployed on day one – reducing the time, effort and cost required to build such environments from scratch.
PAVE360 Automotive using Arm
Following prior collaboration with Arm which resulted in accelerated virtual environments for its Arm Cortex-A720AE in 2024 and Arm Zena Compute Subsystems (CSS) in 2025, Siemens is now further integrating Arm Zena CSS with PAVE360 Automotive to enable the industry to start building on Arm faster and more seamlessly than ever before. Access to Arm Zena CSS in a digital twin environment like PAVE360 Automotive accelerates the development of software by up to two years.
“As vehicles become increasingly AI-defined, automakers and silicon partners need new ways to manage rising complexity without slowing innovation,” said Suraj Gajendra, vice president of products and solutions, Physical AI Business Unit, Arm. “With Arm Zena CSS available inside Siemens’ pre-integrated PAVE360 Automotive environment, partners can not only customize their solutions leveraging the unique flexibility of the Arm architecture but also validate and iterate much earlier in the development cycle, helping them get to market sooner.”
