    Abstract: A system that includes multiple integrated circuits is disclosed. A first integrated circuit of the system includes a plurality of circuit blocks, and a first circuit block of the plurality of circuit blocks includes a first power terminal. A second integrated circuit of the system includes multiple voltage regulation circuits, a second power terminal coupled to an output of a given voltage regulation circuit, and a third power terminal coupled to an input of the given voltage regulation circuit. A substrate, included in the system, includes a plurality of conductive paths, each of which includes a plurality of wires fabricated on a plurality of conductive layers. The system further includes a power management unit that may be configured to generate a power supply voltage at a fourth power terminal that is coupled to the third power terminal via a first conductive path of the plurality of conductive paths.
