Abstract: Aspects of the present disclosure provide techniques and apparatus for safety monitoring of a vehicle control system. An example method of operating a vehicle includes detecting an error associated with a system-on-a-chip (SoC) having a main domain and a safety domain, wherein the main domain is coupled to a first bus for communicating with one or more electronic control units (ECUs) and wherein the safety domain is coupled to a second bus for communicating with the one or more ECUs; indicating the error to the one or more ECUs via at least one of the first bus, the second bus, or a power management integrated circuit (PMIC) in response to detecting the error, wherein the PMIC is configured to supply power to the main domain or the safety domain; and performing one or more actions in response to detecting the error.

Abstract: Techniques and apparatus for power supply monitoring in in-vehicle systems, such as advanced driver assistance systems (ADASs), in-vehicle infotainment (IVI) systems, and/or automated driving (AD) systems. One example method of power supply monitoring generally includes regulating power to a main domain of a system on a chip (SoC) using at least one main domain (MD) power management integrated circuit (PMIC); regulating power to a safety domain of the SoC using at least one safety domain (SD) PMIC; powering the at least one SD PMIC using a SD PMIC power supply rail; and monitoring the SD PMIC power supply rail using the at least one MD PMIC. For certain aspects, the method further includes powering the at least one MD PMIC using a MD PMIC power supply rail and monitoring the MD PMIC power supply rail using the at least one SD PMIC.
