  • Patent number: 11831486
    Abstract: Mechanisms for out-of-band (OOB) management of Field Programmable Gate Array (FPGA) bitstreams and associated methods, apparatus, systems and firmware. Under a first OOB mechanism, a management component, such as a baseband management controller (BMC) is coupled to a processor including an agent in a compute node that includes an FGPA. An FPGA bitstream file is provided to the BMC, and the agent reads the file from the BMC and streams the FPGA bitstream contents in the file to the FPGA to program it. Under second and third OOB mechanisms, a pointer to an FPGA bitstream file that identifies the location of the file that is accessible via a network or fabric is provided to the BMC or other management entity. The BMC/management entity forwards the pointer to BIOS running on the compute node or an agent on the processor. The BIOS or agent then uses the pointer to retrieve the FPGA bitstream file via the network or fabric, as applicable, and streams the FPGA bitstream to the FPGA to program it.

  • Publication number: 20130339789
    Abstract: Methods and apparatus for output of high-bandwidth debug data/traces in electronic devices using embedded high-speed debug port(s). Debug data is received from multiple blocks and buffered in a buffer. The buffer's output is operatively coupled to one or more high-speed serial I/O interfaces via muxing logic during debug test operations. The buffered data is encoded as serialized data and sent over the one or more high-speed serial I/O interfaces to a logic device that receives serialized data and de-serializes it to generate parallel debug data that is provided to a debugger. The buffer may be configured as a bandwidth-adapting buffer that facilitates transfer of debug data that is received at a variable combined data rate outbound via the one or more high-speed serial I/O interfaces at a data rate corresponding to the bandwidth of the serial I/O interfaces.

    Abstract: Embodiments are directed to a method of embedding configuration files in a document generated by a system, with the configuration file including settings associated with the generation of the document. A particular embodiment is directed to the embedding of configuration files of a testing system in a report document generated by the testing system. The configuration file includes system settings and external settings in association with the test results documented in the report document. For example, a testing system can generate a PDF report document associated with a test performed, and embed configuration files into the PDF report document. The embedding of configurations files in the PDF document can be done by using standard embedding mechanisms already available in the PDF file format and supported by most PDF viewing tools. The embedding of the configuration file can be performed automatically when the report document is generated.

    Abstract: A server includes a baseboard management controller (BMC). More than one inter-integrated circuit (I2C) device may be connected to the BMC via a multiplexing switch. The server sets a first identifier for indicating which channels of I2C device are open, and a second identifier for indicating which channels of the I2C devices are closed, and sends the set information to the BMC. To test a selected I2C device, the server opens a channel to the selected I2C device and assigns the first identifier to the channel of the selected I2C device. During testing of the selected I2C device, if the BMC intends to access a different I2C device, the BMC waits for the identifier of the selected I2C device to change from the first identifier to the second identifier, and then opens a channel to the different I2C device.

    Abstract: A parking-structure test system has motherboards that test memory modules. The motherboards are not stationary but are placed inside movable trays that move along conveyors. An unloader removes tested memory modules from test sockets on the motherboards, and a loader inserts untested memory modules into the motherboards using a robotic arm. A conveyor carries the motherboards from the loader to a parking and testing structure. An elevator raises or lowers the motherboards to different parking levels in the parking and testing structure. The motherboards move from the elevator to test stations on the parking level. A retractable connector from the test station makes contact with a motherboard connector to power up the motherboard, which then tests the memory modules. Test results are communicated from the test station to a host controller, which instructs the loader-unloader to sort the tested memory modules once the motherboard returns via the elevator and conveyors.

    Abstract: A testing device for a USB I/O board includes USB plugs connected to the USB I/O board, a connector connected to the USB I/O board, an indication module, and a testing module including data output terminals connected to the USB plugs, data reception terminals connected to the connector, and indication terminals connected to the indication module. The testing module sends a testing signal to the USB I/O board via the data output terminals, and receives the testing signal from the USB I/O board via the data reception terminals. The testing module compares the testing signal to a threshold signal stored in the testing module. If the testing signal and the threshold signal are not substantially the same, the testing module generates an alarm signal to drive the indication module via the indication terminal. The indication module indicates the USB I/O board is abnormal.

    Abstract: A device test architecture and a reduced device test interface are provided to enable efficient testing of embedded cores and other circuits within devices. The reduced device test interface is achieved using a double data rate (DDR) signaling technique between the tester and the device. The DDR test interface allows the tester to interface to test circuits within the device, such as IEEE 1500 and/or IEEE 1149.1 test circuits, to provide high test data bandwidth to the test circuits using a minimum of test interface signals. The test architecture includes compare circuits that allow for comparison of test response data to be performed within the device. The test architecture further includes a memory for storing the results of the test response comparisons. The test architecture includes a programmable test controller to allow for various test control operations by simply inputting an instruction to the programmable test controller from the external tester.
