Abstract

Fault Injection (FI) is a testing method that allows to evaluate system’s ability to manage errors in real-life situations while offering a comprehensive analysis of the system’s robustness and performance under adverse conditions. This is achieved by intentionally introducing errors into a system. FI requires the usage of additional hardware and software, which can be a major problem for smaller startups that lack both employees and budget. This thesis addresses this issue by exploring existing methods and gaps in Fault Injection and designs a cost-effective Fault Injection Unit for the automotive company Meccanica 42. The requirements imposed by them cover functionality, safety, communication, size and form factor of the device. From requirements, a conceptual framework is derived that outlines a hardware-based Fault Injection Unit with fault bus topology. After the device was designed, test results showed that the device passed the functionality requirements and complied with the safety, size and form factor requirements.
