摘要： An approach is provided for testing an Internet of Things device. First data captured on video and indicating visual device output and second data indicating non-visual device output are received during testing of the device. An event log of the device is received. Human interactions with the device are received. The first and second data, the event log entries, and indications of the human interactions are overlaid onto frames of the video that include the device, so that timings of the frames are correlated with timestamps of the overlaid items. Based on the overlaid items, performance, functionality, and usability issues are detected and markers of the issues are generated and overlaid onto a timeline of the video. Responsive to a user selection of one of the markers, the computer locating and displaying a frame of the video that depicts the issue that corresponds to the selected marker.

摘要： A method and system for secure automated deployment of an emulated computer system. The method includes providing a download package for installation on a target machine. The download package includes a generic emulated computer system having no unique identity, no model identity, no features, and minimal processing components. The download package also includes a customer order file based on an order from a customer of the target machine. The customer order file includes a machine identity, at least one machine capability, and control data. The download package also includes at least one enabling key configured to enable the emulated computer system on the target machine. The enabling key is customized based on the order from the customer of the target machine, and includes identity information that restricts the use of the emulated computer system on any computer system other than the target machine. The method also includes delivering the download package to the target machine for installation of the emulated computer system on the target machine. The download package prevents the unauthorized cloning of the emulated computer system onto any hardware platforms other than the target machine, and prevents the unauthorized use of any hardware other than the hardware of the target machine.

摘要： This disclosure describes different ways to improve the operation of a device's 1149.1 TAP to where the TAP can perform at-speed Update & Capture, Shift & Capture and Back to Back Capture & Shift operations. In a first embodiment of the disclosure the at-speed operations are achieved by time division multiplexing CMD signals onto the TMS input to the TAP. The CMD signals are input to a CMD circuit that operates in conjunction with a Dual Port Router to execute the at-speed operations of a circuit. In a second embodiment of the disclosure the at-speed operations are achieved by detecting the TAP's Exit1DR state as a CMD signal that is input to the CMD circuit that operates in conjunction with a Dual Port Router to execute the at-speed operations of a circuit. In a third embodiment of the disclosure the at-speed operations are achieved by detecting the TAP's Exit1DR and PauseDR states and in response producing Capture and Update signals that are input to a Programmable Switch that operates in conjunction with a Dual Port Router to execute the at-speed operations of a circuit. In a fourth embodiment of the disclosure the at-speed operations are achieved by detecting the TAP's Exit1DR and PauseDR states and inputting these states to a Dual Port Router to control the at-speed operations of a circuit. Each of the embodiments may be augmented to include externally accessible Update and Capture input signals that can be selected to allow a tester to directly control the at-speed operations of a circuit. The improvements of the disclosure are achieved without requiring any additional IC pins beyond the 4 required TAP pins, except for examples showing use of additional data input pins (TDI or WPI signals), additional data output pins (TDO or WPO signals) or examples showing use of additional control input pins (Capture and Update signals). Devices including the TAP improvements can be operated compliantly in a daisy-chain arrangement with devices that don't include the TAP improvements.

摘要： Remote computing resource service providers, including online retailer, provide externally facing computer systems that allow users to interact with the service provider. Furthermore, the service provider may maintain computer systems and service inside an isolated network not exposed to users. Occasionally, service providers may test these externally facing computer systems using one or more external hosts operating on a public network. A coordinator may archive aggregated testing resources located on the isolated network and deploy the testing resources to the one or more external hosts. A database may be used to track the deployment state of the one or more external hosts in order to allow the coordinator to manage the testing process.

摘要： Temporary fault injection to existing hardware is performed using only software without changing an implementation of the hardware. A fault injection interrupt process starts on an operation of a CPU using an interrupt that is not used by software, and an internal state of hardware is updated to the same value as a result obtained when a fault has occurred during the interrupt process. A clock of the CPU during the interrupt process is accelerated so that a period of time of the interrupt process is smaller than a period of time until a fault becomes effective.

摘要： A server motherboard diagnosis method, system, and related circuit system. A management module of the server motherboard and peripheral devices managed by the management module are capable of being powered by a server power source and a USB port. In response to the management module and the peripheral devices being powered by the USB port, a power supply line of the server power source is isolated, as by: identifying the peripheral devices, in response to the management module and the peripheral devices being powered by the USB port; for each of the identified peripheral devices, initializing the peripheral device, and then shutting down the power supply of the peripheral device; establishing a communication between the management module and a diagnosis host through the USB port; and executing a command in response to the command being received from the diagnosis host.

摘要： A method is provided to get a high test coverage through a large number of test cases with a minimum number of test programs. Tests are performed flexibly in various environments, using parameters in multiple dimensions. The parameters can be dynamically extracted from the machine or simulator either by controlling scripts or by the test program itself. Multiple ways are offered to execute subsets of the test combinations.

摘要： A method and system are provided for implementing functional verification including generating and running constrained random irritator tests for a multiple processor system and for a processor core with multiple threads. Separate tests are generated, a main test for one thread, and an irritator test for each other thread in the configuration. The main test and each irritator test are saved and randomly mixed then combined together again, where the main thread is not forced to be generated with any particular irritator.

摘要： A system and method for inspecting a testing state includes determining one or more entities to be manipulated during execution of a test of the system, generating an instance of each of the entities using a plurality of entity templates and a plurality of value generators, and executing the test using the generated instances. At least one of the generated instances includes a first value generated randomly. The test is being executed by one or more processors of the system. In some examples, generating an instance of a first one of the entities includes identifying a first one of the entity templates corresponding to a type of the first entity, determining one or more attributes for the first entity based on the first entity template, and generating an instance of each of the attributes using the entity templates and the value generators.
