TestSphere also unifies validation across different test levels by providing a modular and scalable testing environment that supports both virtual and hardware-based testing, including Software-in-the-Loop (SiL), Hardware-in-the-Loop (HiL), and vehicle testing. This harmonization ensures that test cases can be reused across different test levels without major modifications, significantly reducing the time and effort required for validation. The system's modular design allows for easy customization and expansion, adapting to various testing environments and requirements. This flexibility is crucial for managing the complexity of modern auto-motive systems, ensuring efficient, accurate, and scalable testing.

Bringing Validation to the Next Level – Open Source-Based Vehicle Validation

It is crucial to rethink Software-in-the-Loop (SiL) systems to make them more modular and scalable, leveraging cloud technologies to enhance the validation process. Our SiL system is designed with four main components: 

• Simulation Core: Provides a realistic virtual environment for testing
• Interface Provider: Decouples the system, allowing seamless integration and communication between components.
• virtual ECU (vECU): Closely coupled to the interface, enabling focused development and testing of ECU systems.
• Test Framework: Responsible for testing and manipulating data within the system

At the heart of this system lies the Open Simulation Interface (OSI), which ensures consistent and efficient data exchange between all components – critical for robust and efficient validation. 

The unified validation ensures easy handling, maximum flexibility, and uncomplicated scalability in the test and validation process, for example, for new generation SDVs.
