Various embodiments provide for a network layer device, such as a physical layer network device based on an IEEE 802.x network standard, with extended transmission range. In particular, some embodiments enable a network layer device, that is designed to support network data communication in accordance with a known network standard and that comprises an echo cancellation functional component and an equalization functional component designed to support a nominal data rate defined by the known network standard, to communicate data at an alternative data rate that is lower than the nominal data rate and which may or may not be defined by the known network standard.

Various embodiments provide for a unified interface for testing a system, which can include a device under test (DUT). In particular, some embodiments described herein can be used to implement a Unified Test Framework (UTF) that comprises an architecture that provides a unified (or common) software interface to one or more test methods used during a development life cycle of a system. Example test methods can include, without limitation, modeling, verification, simulation, emulation, validation, customer support, and the like.

Disclosed are systems, methods, and non-transitory computer-readable media for protocol independent data unit forwarding. A packet forwarding system receives a data unit comprising a header byte string via an input port. The packet forwarding system parses the data unit based on a header type determined based on the input port, yielding a parsing output describing the header byte string of the data unit. The packet forwarding system updates a metadata item associated with the data unit based on the parsing output and determines a packet forwarding instruction for forwarding the data unit to a destination based on the metadata item associated with the data unit. The packet forwarding system forwards the data unit to the destination based on the packet forwarding instruction and the metadata item associated with the data unit.

Various embodiments described herein provide for narrowband cancellation for a signal received at a receiver in a communication system. In particular, some embodiments implement a narrowband canceller (NBC) that is configured to cancel a narrowband signal from a transmitted signal that is received by a first physical layer device from a second physical layer device over a communication medium.

Disclosed are systems, methods, and non-transitory computer-readable media for distributed processing in a vehicle networking system. A node in the vehicle networking system receives sets of processed sensor data from multiple nodes in the vehicle networking system. Each set of processed sensor data is generated using a first portion of a data processing algorithm on sensor data captured by different sets of sensors of the vehicle networking system. The node performs a second portion of the data processing algorithm based on the sets of processed sensor data received from multiple nodes, yielding a set of processed aggregated sensor data. The node may use the set of processed aggregated sensor data to provide a computer managed feature and/or transmit the set of processed aggregated sensor data to other nodes in the vehicle networking system.

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.

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.

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.

Disclosed are systems, methods, and non-transitory computer-readable media for determining diagnostic coverage for achieving functional safety. A diagnostic coverage determination system employs an optimized process for efficiently determining a diagnostic coverage level of an electronic circuit. The diagnostic coverage determination system generates an optimized netlist that includes a reduced number of nodes by applying one or more node reduction techniques. The diagnostic coverage is determined based on the optimized netlist, thereby reducing the number of nodes that are injected with faults.

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.

Disclosed are systems, methods, and non-transitory computer-readable media for configuration of time-sensitive networks. Time-sensitive networks utilize traffic shaping to provide for efficient and predictable flows of data through the network. A network configuration tool can be used to determine how data should be routed and shaped through the network towards its destination. The network configuration tool calculates the maximum burst size at an output port of a switch by analyzing groups of data flows that pass through the output port, rather than analyzing the data flows individually.
