  • Patent number: 9535121
    Abstract: Described herein are apparatuses and methods for enhancing timing delay fault coverage during testing of functional circuitry. In one embodiment, an apparatus includes functional circuitry for performing functional operations and test logic coupled to the functional circuitry to enhance timing delay fault coverage for the functional circuitry with at-speed test sequences. The test logic includes a plurality of partitions of scan flip-flops and an independent partition scan enable input signal for each partition for enabling or disabling each partition.

  • Patent number: 9536625
    Abstract: User data or constantly toggling functional critical path timing sensors measure delays in actual critical paths that include a RAM. Variable resistors or variable capacitors are added to RAM bit lines for redundant cells to delay bit-line sensing by sense amplifiers. The sense amplifiers' delayed data is compared to non-delayed data from normal selected RAM cells to detect timing failures. Variable resistors or capacitors may also be added between the write drivers and bit lines to delay writing data into the redundant cells. A margin delay adjustment controller sweeps margin delays for constantly toggling paths until failures. A margin delay is then adjusted and added to functional critical paths that carry user data. Functional critical path timing sensors test setup time with the added margin delay. Timing failures cause VDD to increase, while a controller reduces VDD when no failures occur. Actual delays through the RAM adjust VDD.

  • Patent number: 9536038
    Abstract: CAD software examines delays of paths in a design from design engineers and first selects the longest paths. Then all paths that converge with these longest paths are examined for delays, and a fastest converging path is selected for each of the longest paths. The longest paths are again sorted by the fastest converging delay, and paths with slower converging paths are selected to be Functional Critical Paths (FCP's). Functional critical path timing sensors are added to each FCP to test setup time with an added margin delay. When the margined path delays fail to meet setup requirements, the functional critical path timing sensors signal a controller to increase VDD. When no failures occur over a period of time, the controller decreases VDD. The CAD software can replicate some of the FCP's and add toggle pattern generators and timing sensors and a margin controller to adjust the margin delay.

In one embodiment, an apparatus includes functional circuitry for performing functional operations and test logic coupled to the functional circuitry. The test logic enhances timing delay fault coverage for the functional circuitry. The test logic includes scan flip-flops arranged in at least one scan chain and at least one input signal that is generated based on at least one scan override signal for overriding at least one scan enable signal.

  • Patent number: 9400183
    Abstract: An autonomous vehicle may access portions of a map to maneuver a roadway. The map may be split into one or more levels that represent different regions in space. For example, an overpass may be represented by one level while the road below the overpass may be on a separate level. A vehicle traveling on a particular level may use map data that is associated with that level. Furthermore, if the vehicle travels through a warp zone, it may transition from the current level to a destination level and thus begin to use map data associated with the destination level.

  • Patent number: 9261379
    Abstract: Aspects of the disclosure relate generally to generating roadgraphs for use by autonomous vehicles. A computer may receive input defining aspects of a roadway including an intersection with another roadway, one or more traffic control features, and one or more locations at which a vehicle is required to observe at least one traffic signal before entering the intersection. A user may identify the intersection, for example, by tracing a perimeter around the intersection. In response, for each particular location of the one or more locations, the computer may identifying a route through the intersection from the particular location and determine, based on the boundary of the intersection and the particular location, a set of the one or more traffic control features must be observed by the vehicle before entering the intersection. This information may then be used to generate a roadgraph.
