Cars and trucks used to be pretty simple: Mechanics would open the hood, tinker with the engine, and you’d be good to go. But today’s vehicles are increasingly packed with software and computerized systems, with complexity rising at an unprecedented rate. Plano-based Siemens Digital Industries Software says a new solution was needed to help manage the system-level interdependencies of advanced driver-assistance systems, autonomous driving, and in-vehicle infotainment systems.
The company’s answer: its newly launched PAVE360 Automotive technology, a new category of digital twin software that’s pre-integrated and designed as an off-the-shelf offering to address the escalating complexity of automotive hardware and software integration.
Siemens said PAVE360 Automotive empowers automotive manufacturers and suppliers to speed the development of software-defined vehicles with early full-system, virtual integration that mirrors real vehicle hardware and accelerates both application and low-level software development for those key ADAS, AD, and IVI systems mentioned above.

Speeding. time-to-market ‘from months to days’
The “virtual blueprint for digital twin development” removes the need for customers to build their own digital twins before testing software, Siemens said—significantly reducing time to market for critical applications “from months to days.”
“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,” Tony Hemmelgarn, president and CEO of Siemens Digital Industries Software, said in a statement.
“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,” he added.
Collaboration with U.K.-based Arm
Siemens cited its prior collaboration with British semiconductor and software design company Arm Holdings, which resulted in accelerated virtual environments for its Arm Cortex-A720AE in 2024 and Arm Zena Compute Subsystems in 2025. Siemens said it’s 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,” Siemens said.
“As vehicles become increasingly AI-defined, automakers and silicon partners need new ways to manage rising complexity without slowing innovation,” said Suraj Gajendra, VP of products and solutions, physical AI business unit at 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,” Gajendra added, “but also validate and iterate much earlier in the development cycle, helping them get to market sooner.”
