  • Patent number: 11960813
    Abstract: A system and method for automatically generating placement of vias within redistribution layers of a semiconductor package are described. In various implementations, a user defines attributes to use for automatic via generation in redistribution layers of a semiconductor package. The circuitry of a processor of a computing device used by the user executes instructions of an automatic redistribution layer (RDL) via generator. The automatic via generator uses the attributes, data indicative of the RDL netlist of signal routes within the RDL, and RDL mask layout data representing the signal masks of the metal layers within the RDL. The processor generates placement of vias for in the RDL based on the attributes and an identification of overlapping regions between metal layers.

  • Patent number: 11949257
    Abstract: A controller executes an equalization process of equalizing capacities of a plurality of cells, and a cell abnormality determination process of, of detected voltages of the plurality of cells, calculating a voltage difference between a representative voltage based on the detected voltage of at least one cell to be compared and the detected voltage of one cell to be detected at a first time and a second time, and when a difference between the two voltage differences is greater than or equal to a threshold value, determining that the cell to be detected is abnormal. In the case of executing the cell abnormality determination process during the equalization process, the controller provides the detected voltage of a target cell to be subjected to the equalization process with a compensation value corresponding to a voltage change based on energy transfer in the target cell due to the equalization process between the first time and the second time, and calculates the voltage difference at the second time.

  • Patent number: 11941339
    Abstract: Described is technology for automatically generating a routing for an integrated circuit (IC) design. Information describing pin-pairs of an integrated circuit (IC) design is received. An initial routing of the IC design is determined by (i) defining connected wires between each pin-pair in the set of pin-pairs, and (ii) evaluating a target resistance for the pin-pair over the connected wires, wherein each connected wire is routed with other connected wires. A resistance adjustment is applied to adjust wire resistance of the connected wires of the initial routing. The resistance adjustment can be based on a square routing in response to a wire resistance being below the target resistance; or the resistance adjustment can be based on a multi-layer stacking in response to the wire resistance being above the target resistance. The routing is provided in patterns as generated by the initial routing and the resistance adjustment.
