摘要： Disclosed are systems, methods, and non-transitory computer-readable media for a hybrid physical layer that supports data communications using both Ethernet and ASA. Ethernet and ASA are communication standards that are commonly used in automotive environments; however, are not interoperable. The hybrid physical layer supports data communications using both Ethernet and ASA. For example, the hybrid physical layer may be configured into either a first mode of operation to support data communications using Ethernet or a second mode of operation to support data communications using ASA. Devices utilizing the hybrid physical layer can therefore be used with other components that utilize either communication standard.

摘要： Disclosed are systems, methods, and non-transitory computer-readable media for achieving functional safety compliance using a recursive system layer analysis. A functional safety system uses a recursive method to sequentially analyze each layer of a target environment from a bottom layer (e.g., IP layer) to a top layer (e.g., system layer). If a target diagnostic coverage level is not achieved at a given layer, the functional safety system attempts to achieve the target diagnostic coverage level at the next layer based on the residual faults from the lower layer. At the top layer, the functional safety system may apply the context of the target environment to reduce the scope of the coverage analysis based on the given application. The functional safety system may also use the context of the target environment to the reanalyze the lower layers as needed.

摘要： Various embodiments described herein provide for a mechanism for detecting failure in the operation of FEC of a physical layer device, such as a physical layer device of a networking application that seeks to meet a functional safety standard (e.g., ISO 26262). In particular, some embodiments described herein provide one of several methods for detecting a failure in the operation of a FEC decoder of a physical layer device.

摘要： Disclosed are systems and methods for providing in-service testing using a redundant segment. A device (e.g., memory, filter, GPU) is implemented as multiple device segments. For example, a filter including 1024 taps may be implemented as sixteen smaller filter segments that include 64 taps each. A redundant segment that is of similar size to the device segments is used to provide in-service testing of the individual device segments. For example, the redundant segment is provided the same input as a device segment and the output of the redundant segment and the device segment are compared to determine whether the device segment is operating correctly. Multiplexers are used to cycle use of the redundant segment to provide in-service testing of each of the device segments. For example, the multiplexers can be configured into different modes to provide for testing of the various device segments.

摘要： Disclosed are systems, methods, and non-transitory computer-readable media for functional safety of computer networking systems implemented in vehicles. A functional safety system analyzes diagnostic data describing data packet transmissions in a vehicle networking system during a testing mode. The data packet transmissions include predetermined data packet sequences for testing a network feature of the vehicle networking system. The functional safety system determines, based on the diagnostic data, that the network feature of the vehicle networking system is not performing as expected, and generates a functional safety report indicating that the network feature of the vehicle networking system is not performing as expected. The functional safety report including at least a portion of the diagnostic data.

摘要： Disclosed are systems, methods, and non-transitory computer-readable media for a segmented ECF that includes multiple filter components to replicate an echo pulse response. The different filter components are used to replicate different portions of the echo pulse response. Each filter components can include filter coefficients of different sizes based on the portions of the echo pulse response that is replicated by the filter component. For example, a filter component that replicates a portion of the echo pulse response that includes a large reflection can include large filter coefficients suitable to replicate the larger reflection. In contrast, a filter component that replicates a portion of the echo pulse response that includes smaller reflections can include smaller filter coefficients that are suitable to replicate the smaller reflection. The output of each of the filter components is combined to replicate the full echo pulse response.

摘要： Disclosed are systems, methods, and non-transitory computer-readable media for efficient safety mechanism selection for achieving functional safety. A functional safety system automates the process of achieving a target diagnostic coverage level using recursive method to sequentially analyze each layer of a target environment and add additional safety mechanisms if a target diagnostic coverage level is not met. The functional safety system implements the additional safety mechanisms based on a ranking determined based on one or more selected parameters. The parameters may indicate a preference for achieving specified goals, such as higher efficiency, increased coverage, reduced cost, reduced area, and the like. The functional safety system adds the additional safety mechanisms based on the ranking, such as by adding the highest ranked safety mechanism, followed by subsequently ranked safety mechanism.
