  • Patent number: 9300153
    Abstract: The amount of power generated by a solar cell is used for charging more efficiently. An activation determination means 4 activates a charging control circuit 3 by allowing a maximum output current from a solar cell 1 to a GND potential to flow and detecting that the output current is equal to or greater than current consumption of the charging control circuit 3 instead of monitoring an unstable output voltage from the solar cell 1. Thus, the charging control circuit 3 can be activated more precisely in comparison to a case where an output voltage is monitored under the condition that the charging control circuit 3 is operated only by the amount of power generated by the solar cell. Thereby, a power instrument 2 is charged more efficiently with the amount of power generated by the solar cell.

  • Patent number: 9298868
    Abstract: A technique for generating pushdown data comprises performing logical pushdown of circuit elements and nets and detecting physical pushdown based on partition boundary crossings. Geometry associated with one logical level may be used as a keep-out region for the same physical layer when generating physical design of a different logical level. The technique may advantageously enable concurrent design in both top-level and low-level physical design phases, thereby reducing overall design cycle time in developing an integrated circuit.

  • Patent number: 9298862
    Abstract: A system and method optimizes hardware description generated from a graphical program or model automatically. The system may include a streaming optimizer, a resource sharing optimizer and a delay balancing engine. The streaming optimizer transforms one or more vector data paths in the source model to scalar data paths or to a smaller-sized vector data paths. The resource sharing optimizer may replace multiple blocks of the source model that are functionally equivalent with a single shared block. The streaming and resource sharing optimizers may also configure portions of the modified model to execute at a faster rate. The delay balancing engine may examine the modified model to determine whether any delays or latencies have been introduced. If so, the delay balancing engine may insert one or more blocks into the modified model to correct for any data path misalignment caused by the introduction of the delays or latencies.

  • Patent number: 9292643
    Abstract: A method and apparatus for translating a hierarchical IC layout file into a format that can be used by a mask writer that accepts files having a limited hierarchy. Cover cells of the original IC layout file or a modified file are designated, and the hierarchical file is redefined to include only those designated cover cells. Non-designated cover cells and other geometric data are flattened into the designated cover cells. The hierarchy of the modified file is then redefined to be less than or equal to the hierarchy limit of the mask writing tool.

  • Patent number: 9251304
    Abstract: A design tool can implement phase algebra based design evaluation to efficiently evaluate a circuit design with a compact representation of numerous waveforms without simulating the individual waveforms. Instead of individual waveforms, the phase algebra based design evaluation employs compact representations of a group or set of waveforms. Phase algebra based evaluation constructs representations of a set of waveforms based on relationships among a devised set of functions that account for the various states of a signal over time, including transitions and glitches. A memorized-transition function, referred to herein as an M-function, indicates signal transitions over time.
