Abstract: In various examples, a time conversion operation may be performed based at least on updating a first local clock of a component based at least on a reference clock of a system including the component. A difference between a current time of the first local clock and a current time of a second local clock of the component may be determined. A state of at least one of the reference clock, the first local clock, or the second local clock may be determined based at least on comparing the time difference to a previously determined difference between a time of the reference clock and a time of the second local clock.

Abstract: In various examples, confirming or evaluating availability requirements as part of a safety analysis for autonomous and semi-autonomous systems and applications is described herein. For instance, systems and methods are disclosed that may add availability requirements to one or more safety analysis techniques, such as failure mode and effects analysis (FMEA), critical path analysis (CPA), and/or any other safety analysis technique. In some examples, an availability requirement may indicate whether a failure mode associated with a detected failure will impact an availability of an element and/or one or more measures that may be taken to avoid impacting the availability of the element. Systems and methods may then analyze a machine using these updated safety analysis techniques to detect failure modes in a system, causes of the failure modes, and effects of the failure modes, as well as determine whether these failure modes will impact the availability of the system.
