Abstract: An embodiment of a manager includes at least one input node configured to receive information regarding a region of an integrated circuit, and a determiner configured to determine, in response to the information, a likelihood that the region will cause an error. For example, the region may include a memory, and contents of the memory may be transferred to another, more reliable memory, if the likelihood that the memory will cause an error in the data that it stores equals or exceeds a likelihood threshold.

Abstract: In an embodiment, a method includes: receiving, with a first buffer of a first error compactor unit (ECU), a first error packet associated with a first circuit; receiving, with the first buffer, a second error packet associated with a second circuit; transmitting a first reading request for reading the first error packet; receiving the first reading request with an arbiter of an error aggregator unit (EAU) of a central error management circuit; in response to receiving the first reading request, reading the first error packet from the first buffer, transmitting the first error packet to a controller of the central error management circuit, and transmitting a first acknowledgement to the first ECU; receiving the first acknowledgement with the first ECU; and in response to receiving the first acknowledgement, transmitting a second reading request for reading the second error packet.

Abstract: A safety system monitors faults in an embedded control system. The embedded control system is modeled to produce one or more model check values by calculating how many clock cycles will pass between an initialization time point and at least one event time point for a specific event. The initialization time point is a certain point in an initialization function of a scheduler in the embedded control system. The at least one event time point is an expected number of clock cycles to pass before a specific event occurs. In operation, the embedded control system is initialized, a current clock cycle counter value is retrieved at a certain point in the initialization, and either an occurrence or an absence of an occurrence of a scheduled event is recognized. A current clock cycle value is recorded upon the recognition, and a mathematic check value is produced from the clock cycle value stored at the certain point in the initialization and the clock cycle value recorded upon the recognition. Subsequently, the model check value is compared to the mathematic check value, and action is taken based on the comparison.

Abstract: Disclosed herein is hardware for easing the process of changing the execution mode of a virtual machine and its associated resources. By adopting the hardware, it is possible to trigger a change in the execution mode in an automatic way, without software intervention, and without interfering with the execution of other virtual machines. In addition, in case an error has occurred for a virtual machine and it is detected, the hardware can be used to disable the resources associated with that virtual machine and generate notification of the completion this operation to other hardware, which will complete the reset of the virtual machine. By adopting the hardware, the execution mode change is simplified and offers configurability and flexibility for a system running multiple virtual machines.

Abstract: A testing tool includes a clock generation circuit generating a test clock and outputting the test clock via a test clock output pad, data processing circuitry clocked by the test clock, and data output circuitry receiving data output from the data processing circuitry and outputting the data via an input/output (IO) pad, the data output circuitry being clocked by the test clock. The testing tool also includes a programmable delay circuit generating a delayed version of the test clock, and data input circuitry receiving data input via the IO pad, the data input circuitry clocked by the delayed version of the test clock. The delayed version of the test clock is delayed to compensate for delay between transmission of a pulse of the test clock via the test clock output pad to an external computer and receipt of the data input from the external computer via the IO pad.
