  • Publication number: 20190185296
    Abstract: The invention discloses a wind protection anchoring system for a bridge crane and a method, wherein the system comprises four wind protection pull rods mounted on the bridge crane and four ground wind protection foundations corresponding to the four wind protection pull rods; the wind protection pull rod comprises a pull rod body, a pull rod nut, a driving device and a lock pin; the pull rod nut is connected to the pull rod body with threads thereon and mounted on the bridge crane; the top end of the pull rod body is fixedly provided with a driven device and the bottom end is connected to a lock pin; a lock pin fixing groove is formed on the ground wind protection foundation, at which mounted a fixing plate opened with a first opening and a second opening,; the driving device is driven by the wind protection anchoring control module to enable the pull rod body to descend and enter into the lock pin fixing groove through the second opening, and enable the pull rod body to ascend and being blocked by the first

  • Patent number: 10325056
    Abstract: A system, methods, and a computer program product for estimating a yield and creating corners of a circuit design with the aid of a failure boundary classification. The system, methods and computer program product provide for determining, based on how many sampling factors have failures, whether data samples are sufficient as input to scaled-sigma sampling. If the data samples are insufficient, the failure boundary classification is usable to determine whether the yield is high enough to meet a yield target. A design corner can be located by applying a binary search to results of scaled-sigma sampling. The failure boundary classification can aid in setting up the search.

  • Patent number: 10289764
    Abstract: Methods and systems are provided. In one aspect, a method for parallel extraction of worst case corners of a number of electronic design automation (EDA) simulations includes generating multiple initial EDA simulation results for a number of specifications of an integrated circuit based on a first algorithm. For each specification, a respective first set of input samples is generated based on a second algorithm using generated multiple initial simulation results. Using a third algorithm, two or more of the respective first set of input samples are merged based on a criterion to generate a respective second set of input samples. For each specification, a first set of simulation results is generated using the respective second set of input samples. The worst case corners for the specifications are determined by applying in parallel local optimization to the first set of simulation results.
