SAICEC and Siemens: Accelerating Chip-to-Vehicle Validation with Digital Twin Technology

This release outlines how SAICEC’s adoption of Siemens’ PAVE360 is designed to address system-level verification challenges in software-defined vehicle development.

SAICEC is creating digital twins of its automotive architectures using Siemens’ PAVE360 software to establish a comprehensive system-to-chip verification environment. This initiative supports automotive OEMs aiming to accelerate next-generation vehicle development across increasingly complex hardware and software ecosystems.

Key elements highlighted by SAICEC include:

• Development of digital twins for full automotive system architectures.

• Use of Siemens’ PAVE360 to support chip-to-vehicle validation workflows.

• Enablement of system-to-chip level verification earlier in the development cycle.

The collaboration enables automotive manufacturers to address challenges associated with Advanced Driver Assistance Systems (ADAS) and In-Vehicle Infotainment (IVI), where late-stage hardware availability often limits the ability to validate performance and safety requirements. By enabling earlier verification, the approach helps reduce costly redesigns and supports more predictable development timelines.

This capability is supported by:

• A scalable validation environment that provides multi-fidelity system modeling.

• Integration of system-level digital twins with reference vehicle setups.

• Support for early-stage functional validation before hardware is available.

As SDV programs introduce greater architectural complexity, automotive hardware and software teams often work across isolated environments, limiting access to a unified system view. This creates bottlenecks when final hardware does not meet certification requirements. Earlier validation through digital twins is becoming foundational to achieving the scale, safety and reliability expected in modern mobility programs. This reflects a broader industry shift toward simulation-first development across automotive platforms.

PAVE360 combines Siemens’ Innexis software environment with supporting technologies to create system-level digital twins for ADAS and IVI capabilities. These models can connect to physical or simulated reference vehicles, allowing users to validate critical functions from the earliest design stages. OEMs and suppliers can use this workflow to support chip selection, accelerate integration and strengthen overall system design maturity.
