Design, Implementation and Verification of the End of Line Test for an Automotive Instrument Cluster

The topic of this work of thesis is the development of the End of Line test process for a sport car instrument cluster. There will be insights into the production process of the system and the machinery that is available for the execution of the test, as well as deeper analysis on the product itself and its failure modes. The exposition will then follow a more practical course, regarding the actual way in which every part of the test is engineered and implemented, starting from the electrical tests to the optical ones, highlighting the main issues and the timings of the whole process. Directly after the end of the test design there will be a short in-depth analysis on the validation process, which involves injecting artificial faults in the device in order to validate the test itself. Eventually we will fast forward to the completed test and analyze its performances around some key statistical indicators with the purpose of verifying both the production and the testing processes capabilities. In conclusion you will find a brief description of a new software tool designed to assist the testing engineer in the composition of the test sequence, complete with the description of its features and the presentation of an early prototype.
