  • Patent number: 12277376
    Abstract: To ensure proper operation (e.g., speed and/or function) of standard cells fabricated within an integrated circuit a minimum potential difference between the high and low power supply rails needs to be maintained. IR drop refers to a reduction in the potential difference between the power supply rails and is caused when the switching activity of cells that share a power supply rail is greater than can be provided at a particular time. Before fabrication, placement of the cells is reorganized within bounding box regions. Power density across the power rails within each bounding box is normalized based on spatial and temporal power density characteristics of each cell. The reorganization is IR aware and has minimal impact on timing and IR drop is mitigated because distributing current consumption between the supply rails reduces current spikes and IR drops.

  • Publication number: 20250103076
    Abstract: Reference voltage generators including a header circuit configured to pass current from a power supply to a time-to-digital converter, an amount of the current to pass determined by a thermometer code, and logic to update the thermometer code based on a comparison between an output of the time-to-digital converter and a digital code representing a reference voltage level.

  • Publication number: 20250105734
    Abstract: Power delivery systems for integrated circuits that include a first metal path traversing first metal layers from a global power domain supply to a voltage regulator, a second metal path traversing second metal layers from a local power domain supply to the voltage regulator, and a third metal path traversing third metal layers from the local power domain supply to an integrated circuit. Electrical isolation gaps are formed between the first metal layers, the second metal layers, and the third metal layers.
