The platform integrates Arm Zena CSS, targets ADAS, automated driving and IVI and is set for general availability in February 2026.
Siemens unveiled its PAVE360 Automotive technology, which it describes as a pre-integrated digital twin software offering intended to help manage the complexity of automotive hardware and software integration.
Siemens said PAVE360 Automotive supports development of software-defined vehicles through early full-system virtual integration that models vehicle hardware and can support application and low-level software development for ADAS, automated driving and in-vehicle infotainment. The company said this approach reduces the need for customers to build digital twin models before software testing and can shorten development timelines.
As vehicle hardware and software become more complex, development teams face pressure to deliver new features while managing dependencies among ADAS, automated driving and infotainment functions. Siemens said traditional development methods may not address these system-level interdependencies and that a different approach is needed.
PAVE360 Automotive: A virtual blueprint for digital twin development
PAVE360 Automotive uses Siemens’ digital twin technology to support automakers by enabling them to:
- Start vehicle systems development early with customizable virtual reference designs for ADAS, automated driving and IVI
- Use a single digital twin to support development and cloud-based collaboration across teams
- Customize and scale by adding software, models and external hardware as needed
- Accelerate software development using simulation speed intended to approximate hardware performance, including support for automotive IP such as the Arm Zena Compute Subsystem (CSS)
- Validate designs by linking digital twins to physical hardware and testing in vehicles
Developing and validating system-level digital twins for software-defined vehicles can be complex and time-consuming. Siemens says PAVE360 Automotive provides an integrated system-level digital twin environment that can be deployed at the start of a program, reducing the time, effort and cost of building it from scratch.
PAVE360 Automotive using Arm
Following earlier work with Arm that produced accelerated virtual environments for the Arm Cortex-A720AE in 2024 and Arm Zena Compute Subsystems (CSS) in 2025, Siemens is integrating Arm Zena CSS with PAVE360 Automotive. Siemens said the integration is intended to help users begin development on Arm-based platforms earlier in the process. The company said access to Arm Zena CSS in a digital twin environment such as PAVE360 Automotive can shorten software development timelines by up to two years.
Availability
PAVE360 uses Siemens’ Innexis software environment and related technologies to help users create system-level digital twins of ADAS, automated driving and in-vehicle infotainment capabilities. Siemens said PAVE360 Automotive is available to select customers, with general availability in February 2026. Siemens plans to demonstrate it at CES 2026 in the Auto Hall, Jan. 6-9, 2026.
