  • Publication number: 20240220702
    Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to adjust vias in integrated circuits (ICs) based on machine learning (ML). An example apparatus computes a dimension by which to extend a via based on at least one of a first metal wire in a first layer of the IC above the via, a via-to-via patterning constraint, or a via-to-metal shorting constraint for a second layer of the IC below the via. The example apparatus also computes a shifted position of the via based on at least one of (a) the dimension or (b) a width and a position of a second metal wire below the via, the width and the position predicted by an ML model. Additionally, the example apparatus adjusts a configuration file corresponding to the IC based on at least one of the dimension or the shifted position of the via.

  • Patent number: 11630694
    Abstract: Task scheduling in a computing device may be based in part on voltage regulator efficiency. For an additional task to be scheduled, multiple task scheduling cases may be determined that represent execution of the additional task on each of a number of processors concurrently with one or more other tasks executing among the processors. For each task scheduling case, a regulator input power level for a voltage regulator may be determined based on a performance level indication associated with the additional task, the one or more other tasks executing on the processors, and the efficiency level of each voltage regulator. For each task scheduling case, a total regulator input power level may be determined by summing the regulator input power levels for all voltage regulators. The additional task may be executed on a processor associated with a task scheduling case for which total regulator input power is lowest.
