As electronic system sophistication within mobility solutions increases, so too does the requirement to monitor in-chip conditions, whether that be within the engine bay itself, as a part of radar/lidar systems, or as part of the infotainment infrastructure.

The requirement for energy efficiency, power performance and reliability in high volume manufactured vehicles has also caused in-car monitoring and sensor systems to increase in number and complexity, allowing the dynamic physical conditions to be managed and to optimise against the manufacturing variability of each engine produced. At the semiconductor level, in-chip monitoring allows for self-test, self-diagnosis, providing scheme to enhance the reliability of devices situated within harsh automotive environments.
