Abstract: Systems and techniques for creating a circuit abstraction are described. During operation, an embodiment can identify a set of side loads based on a set of timing paths. According to one definition, a side load of a timing path is a circuit element that is not on the timing path (i.e., the timing path does not pass through the circuit element), but whose input is electrically connected to an output of at least one circuit element that is on the timing path. Next, the embodiment can creating the circuit abstraction by retaining circuit elements and nets on each timing path in the set of timing paths, and retaining an identifier for each side load in the set of side loads. The circuit abstraction can then be used to update timing information during one or more stages of an electronic design automation flow.

Abstract: Techniques and systems for performing clock tree synthesis (CTS) across multiple modes are described. Some embodiments traverse one or more clock trees from the root of each clock tree to a set of sinks of the clock tree. During the traversal, each clock gate can be marked with a traversal level, and each sink can be marked with one or more clocks and one or more modes that are associated with the sink. A task queue can then be created based on the information collected during the clock tree traversal and populated with different types of tasks based on skew balancing requirements across different modes, and the task queue can be provided to a CTS engine to achieve high-quality skew-balanced clock trees across all modes.

Abstract: Embodiments are described in which shaping is integrated with power network synthesis (PNS) for power grid (PG) alignment. Specifically, some embodiments create placement constraints based on the PG that is expected to be created by PNS, and then perform shaping (or perform legalization) on the circuit design based on the placement constraints. This ensures that the physical partitions (e.g., instances of multiply-instantiated-blocks) are aligned with the power grid during shaping.

Abstract: An method, apparatus and machine readable medium are described for intelligently selecting a network interface. An attempt may be made to connect over a first network interface having the highest priority (e.g., WiFi). At the same time, a fallback timer is started. If the attempt to connect over the first network interface does not succeed within a designated timer threshold, then a parallel attempt is made to connect over a second network interface having a lower priority (e.g., cellular). The first network interface over which a connection is successfully made is then used. These techniques may be employed on a per-connection basis. Thus, a first process may successfully connect over the first network interface while a second process may be unsuccessful over the first network interface but may fall back to the second network interface.

Abstract: In order to facilitate reduced power consumption of an electronic device (such as a smartphone) when communicating with another electronic device (such as an access point) in a wireless network, the electronic device may change a frequency of network scans performed by an interface circuit in the electronic device based on a motion profile of the electronic device. In particular, the electronic device may determine the motion profile based on spatial information, such as: acceleration data, orientation data, Global Positioning System data and/or data from the wireless network. Then, the electronic device may change the frequency of the network scans performed by the interface circuit based on the motion profile. In this way, the frequency of the network scans can be reduced when the electronic device is stationary or moving rapidly (such as when a user of the elecuonic device is driving in a car).

Abstract: The described embodiments include a power-management unit that receives and stores a representation of a temperature state of a battery pack from a battery-monitoring mechanism in a battery pack. For example, an interface circuit (such as a single-wire-interface or SWI circuit) may receive the information from the battery-monitoring mechanism via a signal line, and the information may be stored in a memory (such as a non-transitory computer-readable memory). This stored information is then used by a temperature-monitoring mechanism or circuit to determine the temperature state of the battery pack, which may be used to control or gate charging of a battery in the battery pack.

Abstract: A power-management unit is described that allows a common signal line to communicate data between an integrated circuit (which may be external to the power-management unit) and a battery-monitoring mechanism in a battery pack, and to convey a signal that represents a temperature state of the battery pack to a temperature-monitoring circuit or mechanism that monitors the temperature state of the battery pack. The power-management unit may include a single-wire interface or a multiplexer that, at a given time, selectively couples the signal line from the battery pack either to the integrated circuit or the temperature-monitoring circuit based on a control signal provided by the integrated circuit (for example, via an I2C bus or interface). In this way, the power-management unit may reduce the number of signal lines needed to communicate with the battery-monitoring mechanism and to convey the signal.
