  • Publication number: 20230319711
    Abstract: This disclosure describes techniques for renegotiating target wake time (TWT) parameters used for transmitting Bluetooth-encoded audio frames over one or more Wi-Fi channels. In some implementations, a software-enabled access point (softAP) paired with a peripheral device based on a Bluetooth protocol and associated with the peripheral device via a WLAN link transmits one or more first Bluetooth-encoded audio frames indicating a current time-to-play (TTP) value for audio data to the peripheral device over the WLAN link during a first TWT session. The softAP detects a change in the WLAN link, and obtains new TWT parameters and a new TTP value responsive to the detected change. The softAP indicates the new TWT parameters and the new TTP value to the peripheral device in conjunction with tearing down the first TWT session, and establishes a second TWT session with the peripheral device based at least in part on the new TWT parameters.

  • Patent number: 11429770
    Abstract: The present disclosure relates to a computer-implemented method for electronic design verification. Embodiments may include receiving an electronic design at a verification environment. Embodiments may also include performing a simulation of a portion of the electronic design in an X-propagation mode. Embodiments may further include determining whether the simulation is entering an element during a time range and determining whether a clock/reset associated with the element has an active X-edge. If the clock/reset has an active X-edge, embodiments may include preventing a recordation of coverage metrics during the time range.

  • Patent number: 10316468
    Abstract: A multi-faceted family of non-woven webs that can take the form of a filter media, an adaptable forming process and a machine capable of making the range of media are disclosed. The filter medium can have a first surface and a second surface defining a thickness. The medium can comprise a region having a gradient. Such a gradient is formed by having a medium wherein the concentration of a fiber, a property or other component varies from one surface to the next surface. The gradient region of the media can comprise the entire thickness of the medium or can comprise a region that comprises a portion of the media thickness. The media are characterized by the presence of a continuous change of the fiber concentration or property within the region.

  • Patent number: 10031991
    Abstract: The present disclosure relates to a computer-implemented method for electronic design verification. Embodiments may include receiving an electronic design environment including both a design under test (“DUT”) and a testbench. Embodiments may further include simulating an electronic design associated with the electronic design environment and generating a coverage database associated with the electronic design. Embodiments may include performing coverage analysis of the DUT and testbench using an automated inheritance aware analysis and applying the coverage analysis results to the testbench after simulation.

  • Patent number: 9824175
    Abstract: A method for automatically verifying validity of application of a refinement rule includes calculating a set of values that characterize a hierarchy of elements of the emulation. A currently calculated value for a first element at a first level of the hierarchy is compared with a previously calculated value that characterized the first element at a previous time. If the currently calculated value is the same as the previously calculated value, application of the refinement rule is determined to be valid for unnamed entities of the first element. If the currently calculated value is different from the previously calculated value, each currently calculated value that characterizes a lower level element at a lower level of the hierarchy is compared with a corresponding previously calculated value to identify a change and it is determined whether the change invalidates application of the refinement rule to an unnamed entity of the emulation.

  • Patent number: 9582620
    Abstract: A computer implemented method and system for exclusion of entities from a metric driven verification analysis score. The method includes using a processor, and performing the following steps: parsing a source code simulating a device under test and modeling the source code into a model that includes entities of one or a plurality of metric driven entity types; identifying in the source code entities of the same metric driven entity type of said one or a plurality of metric driven entity types that are logically linked and saving information on the identified entities that are logically linked; receiving from a user a selection of an entity to be excluded from the metric driven verification analysis score; and excluding all instances of the selected entity and all instances of the identified entities that are logically linked to the selected entity from a calculation of the metric driven verification score.

  • Publication number: 20160285952
    Abstract: Data can be conveyed between devices in a wireless personal area network. At a first device in the wireless personal area network, a request for the data can be received from a second device in the wireless personal area network. The data can be encoded for storage in a computer file using a file format that lacks data compression. A determination can be made whether the second device is configured to decompress the data. The data can be compressed in response to the determination that the second device is configured to decompress the data. The data can be transmitted from the first device to the second device.
