Zusammenfassung:Methods and systems are disclosed for clock delay compensation in a multiple chiplet system. Techniques disclosed include distributing, by a clock generator, a clock signal across distribution trees of respective chiplets; measuring phases, by phase detectors, where each phase measurement is associated with a chiplet of the chiplets and is indicative of a propagation speed of the clock signal through the distribution tree of the chiplet. Then, for each chiplet, techniques are further disclosed that determine, by a microcontroller, based on the phase measurements associated with the chiplet, a delay offset, and that delay, based on the delay offset, the propagation of the clock signal through the distribution tree of the chiplet using a delay unit associated with the chiplet.
