Abstract: A method includes determining vehicle driving parameters associated with a driving behavior of a vehicle while in an autonomous driving mode. A plurality of electronic control units (ECUs) is interconnected to a vehicle bus for communicating instructions from electromechanical contacts to actuators to control the driving behavior. The computing unit may receive a control signal from one of the ECUs. The computing unit lacks knowledge of whether the control signal a valid. The method further includes analyzing vehicle driving parameters associated with the driving behavior to determine whether the vehicle driving parameters satisfy a driving behavior criteria. Subsequent to determining that the vehicle driving parameters fails to satisfy the driving behavior criteria, the method includes generating a signal that causes the electromechanical contacts to disconnect from the vehicle bus and disable communication of instructions between the ECUs and the vehicle bus.

Abstract: The present disclosure relates to a system and method for maintaining coherency in the memory subsystem of an electronic system modeled in dual abstractions. Embodiments may include providing a mixed abstraction simulation model including an abstract portion and a detailed portion, wherein the detailed portion includes a cache coherent interconnect and a coherency proxy. Embodiments may further include establishing, within the detailed portion, communication between an extended smart memory function and at least one of the cache coherent interconnect and the coherency proxy. Embodiments may also include determining, via the extended smart memory function, a status of at least one cache memory associated with the mixed abstraction simulation model. Embodiments may further include automatically maintaining, via the extended smart memory function, a coherent view of a system memory for the abstract portion and the detailed portion of the mixed abstraction simulation model.

Abstract: A system and method are provided for offloaded lateral transmission between protocol interface devices in an electronic system. Such offloading allows the lateral transmission of data and/or instructions between disparate protocol interface devices without burdening the electronic system's resources, such as the primary processor, memory, and/or system bus. A lateral communication controller is provided to intercouple the first and second protocol interface devices and selectively intercept data packets from one device to be injected into another.
