XX Diagnostics on Gigabit Speed SerDes Video Links
The fast paced development of Advanced Driver Assistance Systems (ADAS) in the automotive industry, boost the demand for ways of ensuring safe and reliable systems. With the increased data speed of video links, connecting the high resolution cameras with their Electrical Control Units (ECU) ADAS are becoming more sensitive to electromagnetic disturbances. Due to this sensitivity, the conditions of video links in the car should be investigated continuously to ensure the safety and reliability. The outcome of this thesis is the concept Simons Video Interference Check (SIVIC) which is designed to be a technique for diagnostics on video links. The SIVIC concept is able to continuously record video link quality data, detect trends of deteriorating behaviour, detect and distinguish multiple types of disturbances as well as detect video link failures. The SIVIC concept was implemented as a proof of concept tested on two different test rigs based on the technology Gigabit Multimedia Serial Link (GMSL) One of the test rigs contained a parking assist camera, which is developed to be included in a vehicle and representing a real system used in the automotive industry. The video link failure detection was tested by real world tests in a lab at Research Institute of Sweden (RISE) and all other functionality were tested by using software. The SIVIC concept proves how a software module can be used to detect and predict data link failure of high speed automotive video links.
