Abstract:
Siemens Digital Industries Software deepens its collaboration with Arm, integrating Arm’s Zena CSS into its PAVE360 software to accelerate the development of Software Defined Vehicles (SDVs).At the Siemens Realize LIVE 2025 conference held last week in Detroit, Siemens Digital Industries Software announced the enhancement of its partnership with Arm, integrating Arm’s Zena Compute Subsystem (CSS) into its PAVE360 software aimed at Software Defined Vehicles (SDVs).
Realize LIVE is Siemens Digital Industries Software’s major annual customer conference, which took place in Detroit from June 2-5 this year.
The Arm Zena Compute Subsystem (CSS) is the first pre-integrated and pre-validated computing platform designed by Arm specifically for AI Defined Vehicles (AIDVs), aimed at accelerating automotive chip development and simplifying the complex processes of Software Defined Vehicles (SDVs).
PAVE360 serves as a core component of Siemens’ Software Defined Vehicle (SDV) framework, integrating the Innexis software environment, Veloce hardware-assisted verification system, product lifecycle management software Teamcenter, application lifecycle management platform Polarion, and simulation tools Simcenter Prescan and Simcenter Amesim, providing a more integrated solution for software-defined development.Suraj Gajendra, Vice President of Automotive Products and Software Solutions at Arm, stated:“The era of AI Defined Vehicles presents opportunities for innovation in in-vehicle experiences, but the speed of development and deployment must be significantly increased. With Siemens’ PAVE360 and other virtual platform solutions, Arm’s users can initiate software development based on Zena CSS before chip tape-out, significantly shortening the development cycle for new software solutions.”This is akin to simulating cooking before the kitchen is even built.David Fritz, Vice President of Siemens Digital Industries Software, remarked:“The collaboration with Arm demonstrates that merely achieving software-defined product development is insufficient—development processes must upgrade to a system-level parallel mode, where the entire vehicle system is developed in parallel to ensure global requirements are met and continuously validated. Siemens helps customers build a multi-domain (electronic, hardware, application development) parallel digital twin that covers System on Chip (SoC), electronic and electrical (E/E) architecture, and the entire vehicle development process, enabling validation and integration.”According to Siemens, customers can now develop software for Zena CSS through PAVE360 before chip mass production. In the SOAFEE open-source community, this virtual prototyping environment will become a key technology for realizing the SOAFEE blueprint.Users can execute system-level software function validation, accurately model SoC algorithms and hardware-software interactions, thereby addressing challenges in software-defined and system-level parallel development.
Siemens initially supported Arm’s Zena CSS through native acceleration based on the Innexis architecture (ANA), and this functionality has now been released as a component of Siemens PAVE360. Automotive customers can immediately start software development and seamlessly switch to Innexis Developer Pro for precise performance and power analysis once the chips are ready. Meanwhile, PAVE360 provides system-level parallel digital twins by correlating requirements and verification data, effectively alleviating the system integration challenges currently faced by developers.References:
