摘要： Manufacturers perform tests on chips before the chips are shipped to customers. However, defects can occur on a chip after the manufacturer testing and when the chips are used in a system or device. The defects can occur due to aging or the environment in which the chip is employed and can be critical; especially when the chips are used in systems such as autonomous vehicles. To verify the structural integrity of the IC during the lifetime of the product, an in-system test (IST) is disclosed. The IST enables self-testing mechanisms for an IC in working systems. The IST mechanisms provide structural testing of the ICs when in a functional system and at a manufacturer's level of testing. Unlike ATE tests that are running on a separate environment, the IST provides the ability to go from a functional world view to a test mode.

摘要： Several methods may be used to exploit the natural physical variations of sensors, to generate cryptographic physically unclonable functions (PUF) that may strengthen the cybersecurity of microelectronic systems. One method comprises extracting a stream of bits from the calibration table of each sensor to generate reference patterns, called PUF challenges, which can be stored in secure servers. The authentication of the sensor is positive when the data streams that are generated on demand, called PUF responses, match the challenges. To prevent a malicious party from generating responses, instructions may be added as part of the PUF challenges to define which parts of the calibration tables are to be used for response generation. Another method is based on differential sensors, one of them having the calibration module disconnected. The response to a physical or chemical signal of such a sensor may then be used to authenticate a specific pair of sensors.

摘要： A system and method for inspecting system state during testing includes determining one or more inspection modules for examining respective portions of a state of the system using a test inspector, initializing each of the inspection modules, saving the respective portions of the state of the system using the inspection modules, executing a test of the system, checking the respective portions of the state of the system using the inspection modules, and repeating the saving, executing, and checking for each additional test of the system. The test inspector is executed by one or more processors of the system. In some examples, saving a first one of the respective portions of the state of the system includes determining state variables and corresponding values associated with the first respective portion of the state of the system and saving the state variables and corresponding values in a state repository.

摘要： An information processing device includes a processor configured to perform a diagnosis of hardware of the information processing device. The processor is configured to generate plural pieces of failure information. The plural pieces of failure information are classified into groups corresponding to different importance levels. The processor is configured to store the plural pieces of failure information in consecutive storage areas. The consecutive storage areas are divided into storage sections corresponding to the respective groups in order of importance level. The processor is configured to store first piece of failure information in a head of a second storage section in absence of free areas in first storage section. The first storage section is secured for a first group including the first piece of failure information. The second storage section is secured for a second group corresponding to a second importance level lower than the first importance level by one level.

摘要： Systems and methods for smart diagnoses and triage of failures with identity continuity. In some embodiments, an Information Handling System (IHS) includes a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: execute a Power-On Self Test (POST) routine; in response to a determination that the POST routine has failed, execute a firmware-based diagnostics routine; in response to a determination that the firmware-based diagnostics routine has failed, execute, via a service Operating System (OS), a service OS-based diagnostics routine configured to identify whether the firmware-based diagnostics failure is due to a hardware or software fault; and in response to the service OS-based diagnostics routine identifying a hardware fault or failing to remediate a software fault, obtain a user's account information and report the hardware fault or the software remediation failure.
