Publication number: 20250137211Abstract: Systems, computer program products, and methods are described herein for automated data retrieval from an integrated circuit (IC). An example system extracts, using a scan island (e.g., a partition of the IC that is isolated for data retrieval), data from a plurality of scan chains and a plurality of random-access memories (RAMs) associated with the IC in response to a trigger event associated with the IC; determines, using a data security module associated with the scan island, whether the one or more users are authorized to access the respective portions of the data; and transmits the one or more portions of the data to the one or more users upon verification of their authorization.Type: ApplicationFiled: November 4, 2024Publication date: May 1, 2025Applicant: NVIDIA CORPORATIONInventors: Padmanabham Patki, Jue Wu, Andrew Elias, Smbat Tonoyan

Publication number: 20250123329Abstract: A scan island for automated data retrieval from an integrated circuit (IC) includes a data extraction module configured to extract data from multiple scan chains and random-access memory (RAM) modules in response to a trigger event, storing the data in an external non-volatile storage medium. The scan island further comprises a clock and reset module, which includes a free-running independent clock to enable continuous operation of the scan island upon occurrence of the trigger event, and a local reset module that re-initializes the scan island in a known state following the trigger event without external intervention. The scan island operates as an isolated partition within the IC, ensuring secure and autonomous data retrieval and recovery processes.Type: ApplicationFiled: December 27, 2024Publication date: April 17, 2025Applicant: NVIDIA CORPORATIONInventors: Padmanabham Patki, Jue Wu, Andrew Elias, Smbat Tonoyan

Patent number: 12210770Abstract: Systems, computer program products, and methods are described herein for automated data retrieval from an integrated circuit (IC). An example system receives an alert indicating a trigger event associated with the IC; extracts, using a scan island (e.g., a partition of the IC that is isolated for data retrieval), data from a plurality of scan chains and a plurality of random-access memories (RAMs) associated with the IC in response to receiving the alert; stores the data in an external non-volatile storage media; and reboots the IC upon storing the data in the external non-volatile storage media. In this way, embodiments of the present invention offer a scalable and secure method for real-time data extraction and processing in the event of an integrated circuit malfunction, improving diagnostics while ensuring cost-effectiveness and data security.Type: GrantFiled: September 26, 2023Date of Patent: January 28, 2025Assignee: Nvidia CorporationInventors: Padmanabham Patki, Jue Wu, Andrew Elias, Smbat Tonoyan

Publication number: 20240419568Abstract: 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.Type: ApplicationFiled: August 26, 2024Publication date: December 19, 2024Inventors: Jonah Alben, Sachin Idgunji, Jue Wu, Shantanu Sarangi

Patent number: 11810632Abstract: 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.Type: GrantFiled: August 22, 2022Date of Patent: November 7, 2023Assignee: NVIDIA CorporationInventors: Anitha Kalva, Jue Wu

Patent number: 11768241Abstract: 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.Type: GrantFiled: December 20, 2022Date of Patent: September 26, 2023Assignee: NVIDIA CorporationInventors: Anitha Kalva, Jue Wu

Patent number: 11669421Abstract: 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.Type: GrantFiled: February 2, 2022Date of Patent: June 6, 2023Assignee: NVIDIA CorporationInventors: Jonah M.
