aiSim 5 is a premier simulation tool tailored for ADAS (Advanced Driver Assistance Systems) and automated driving validations. As the world's first ISO26262 ASIL-D certified simulator, aiSim 5 employs state-of-the-art AI-based digital twin technology. This enhances its capability to simulate complex driving scenarios with high precision, making it an ideal environment for testing AD systems. The simulator boasts a proprietary rendering engine that provides a deterministic and high-fidelity virtual reality where sensor simulations can cover diverse climatic and operational conditions, such as snow, rain, and fog, ensuring results are reproducible and reliable.\n\naiSim 5's architecture is designed for flexibility, allowing seamless integration with existing development toolchains, and thus minimizing the need for expensive real-world testing. It features a comprehensive 3D asset library that includes detailed environments, vehicles, and scenarios, which can be customized to generate synthetic data for testing. The solution supports multi-sensor simulations, providing a rich testing ground for developers looking to refine and validate their software stacks.\n\nThanks to its modular C++ and Python APIs, aiSim 5 can be easily deployed within any System under Test (SuT) and CI/CD pipeline, enhancing its adaptability across various automotive applications. Additionally, its open SDK facilitates developer customizations, ensuring aiSim 5 remains adaptable and user-friendly. With built-in scenario randomization, users can efficiently simulate a wide array of driving conditions, making aiSim 5 a powerful tool for ensuring automotive system safety and accuracy.
