ASAM XIL is an API standard for the communication between test automation tools and test benches. The standard supports test benches at all stages of the development and testing process – most prominently model-in-the-loop (MIL), software-in-the-loop (SIL) and hardware-in-the-loop (HIL). The notation "XIL" indicates that the standard can be used for all "in-the-loop" systems. This has the advantage that it enables users to freely choose testing products according to their requirements and integrate them with little effort. Using ASAM XIL-compliant products allows users of test systems to mix and match the best components from different suppliers without having costly integration efforts.
The standard furthermore decouples test-cases from real and virtual test systems. This allows to transfer tests between different test systems with little to no migration effort. Consequently, tests can be easily re-used. Know-how is much easier transferred from one test bench to another, resulting in reduced training costs for development- and test engineers.
These advantages are the result of two major components of the ASAM XIL standard:
Test automation applications, which use the ASAM XIL API, are used in all automotive E/E domains, e.g. drivetrain, steering, electric lighting, etc. Cross tests for ASAM XIL implementations are carried out regularly to ensure compatibility between test automation software and test benches.
The standard comes with a C# source code library, which contains open source software that can be used by framework developers to implement the XIL API. It covers about 69% of the standard's API methods. Provided methods are unit and data type conversion, reading mapping files, mathematical operations, and more. The source code has been professionally developed and constitutes a standard-compliant implementation of significant parts of the ASAM XIL API.
