  • Patent number: 11204849
    Abstract: In various examples, one or more components or regions of a processing unit—such as a processing core, and/or component thereof—may be tested for faults during deployment in the field. To perform testing while in deployment, the state of a component subject to test may be retrieved and/or stored during the test to maintain state integrity, the component may be clamped to communicatively isolate the component from other components of the processing unit, a test vector may be applied to the component, and the output of the component may be compared against an expected output to determine if any faults are present. The state of the component may be restored after testing, and the clamp removed, thereby returning the component to its operating state without a perceivable detriment to operation of the processing unit in deployment.

  • Publication number: 20210341537
    Abstract: In various examples, a test system is provided for executing built-in-self-test (BIST) on integrated circuits deployed in the field. The integrated circuits may include a first device and a second device, the first device having direct access to external memory, which stores test data, and the second device having indirect access to the external memory by way of the first device. In addition to providing a mechanism to permit the first device and the second device to run test concurrently, the hardware and software may reduce memory requirements and runtime associated with running the test sequences, thereby making real-time BIST possible in deployment. Furthermore, some embodiments permit a single external memory image to cater to different SKU configurations.

  • Publication number: 20210157699
    Abstract: Unavoidable physical phenomena, such as an alpha particle strikes, can cause soft errors in integrated circuits. Materials that emit alpha particles are ubiquitous, and higher energy cosmic particles penetrate the atmosphere and also cause soft errors. Some soft errors have no consequence, but others can cause an integrated circuit to malfunction. In some applications (e.g. driverless cars), proper operation of integrated circuits is critical to human life and safety. To minimize or eliminate the likelihood of a soft error becoming a serious malfunction, detailed assessment of individual potential soft errors and subsequent processor behavior is necessary. Embodiments of the present disclosure facilitate emulating a plurality of different, specific soft errors. Resilience may be assessed over the plurality of soft errors and application code may be advantageously engineered to improve resilience.

  • Publication number: 20210151118
    Abstract: In various examples, a test system is provided for executing built-in-self-test (BIST) according to JTAG and IEEE 1500 on chips deployed in-field. Hardware and software selectively connect onto the IEEE 1500 serial interface for running BIST while the chip is being used in deployment—such as in an autonomous vehicle. In addition to providing a mechanism to connect onto the serial interface, the hardware and software may reduce memory requirements and runtime associated with running the test sequences, thereby making BIST possible in deployment. Furthermore, some embodiments include components configured to store functional states of clocks, power, and input/output prior to running BIST, which permits restoration of the functional states after the BIST.

  • Patent number: 10281524
    Abstract: In one embodiment, a test system comprises: a test partition configured to perform test operations; a centralized test controller for controlling testing by the test partition; and a test link interface controller configured to communicate between the centralized test controller and the test partition, wherein the test link interface controller controls dynamic changes to external pads associated with the test operations. The test link interface controller dynamically selects between an input direction and output direction for the external pads. The test link interface includes a pin direction controller that generates direction control signals based on the state of local test controller and communicates the desired direction to a boundary scan cell associated with the pin. The boundary scan cell programs the pad to either input or output direction depending on direction control signals. The input direction corresponds to driving test data and the output direction corresponds to observing test data.

  • Patent number: 7747915
    Abstract: A system and method for increasing the yield of integrated circuits containing memory partitions the memory into regions and then independently tests each region to determine which, if any, of the memory regions contain one or more memory failures. The test results are stored for later retrieval. Prior to using the memory, software retrieves the test results and uses only the memory sections that contain no memory failures. A consequence of this approach is that integrated circuits containing memory that would have been discarded for containing memory failures now may be used. This approach also does not significantly impact die area.
