  • Patent number: 11275881
    Abstract: The present disclosure relates to a computer-implemented method for electronic design is provided. Embodiments may include receiving, using at least one processor, an electronic design having one or more unoptimized nets. Embodiments may further include applying a genetic algorithm to the electronic design, wherein the genetic algorithm includes a multi-stage routing analysis. A first stage analysis may apply a device-level global routing analysis, a second stage analysis may include an intra-row routing analysis, a third stage may include an inter-row routing analysis, and a fourth stage may include a post-routing optimization analysis. Embodiments may also include generating an optimized routing of the one or more unoptimized nets and displaying the optimized routing at a graphical user interface.

  • Patent number: 10437954
    Abstract: The present disclosure relates to a system and method for electronic design recommendations. Embodiments may include receiving, using at least one processor, an electronic design. Embodiments may further include recognizing one or more circuits within the electronic circuit design. Embodiments may also include identifying one or more user-specific circuit performance preferences. Embodiments may further include generating a first set of one or more placement and routing topology recommendations based upon, at least in part, the one or more user-specific circuit performance preferences. Embodiments may also include receiving a selection of at least one of the placement and routing topology recommendations. Embodiments may further include generating a second set of one or more placement and routing topology recommendations based upon, at least in part, the selected at least one placement and routing topology recommendations.

  • Publication number: 20130042618
    Abstract: A power unit includes two or more power modules (1, 2, 3), each comprising an engine (11), a transfer case (12) connected to the engine (11) and a hydraulic pump set (13) connected to the transfer case (12). A controlling method for the power unit is also disclosed. Compared to the prior art of using a single super high power engine, the hydraulic mobile crane using the in power unit has advantages of low cost, high reliability, and not being subjected to the restrictions by road transportation conditions during transportation.
