Safety monitoring of a system-on-a-chip

An apparatus for operating a vehicle, comprising:

• 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;
• and
• a power management integrated circuit (PMIC) configured to supply power to the main domain or the safety domain, wherein at least one of the SoC or the PMIC is configured to:
• detect an error associated with the SoC,
• indicate the error to the one or more ECUs via at least one of the first bus, the second bus, or the PMIC in response to detecting the error, wherein to indicate the error:
• the main domain is configured to indicate the error via the first bus in response to the error being associated with the safety domain;
• and
• the safety domain is configured to indicate the error via the second bus in response to the error being associated with the main domain, and perform one or more actions in response to detecting the error.

A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by one or more processors of a processing system, cause the processing system to:

• detect 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;
• indicate 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 wherein to indicate the error:
• the main domain is configured to indicate the error via the first bus in response to the error being associated with the safety domain;
• and
• the safety domain is configured to indicate the error via the second bus in response to the error being associated with the main domain;
• and
• perform one or more actions in response to detecting the error.

An apparatus for operating a vehicle, the apparatus comprising:

• means for 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;
• means for 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 wherein indicating the error comprises:
• indicating the error via the first bus in response to the error being associated with the safety domain;
• and
• indicating the error via the second bus in response to the error being associated with the main domain;
• and
• means for performing one or more actions in response to detecting the error.
