Abstract: A particular three-dimensional integrated circuit stack includes a first die including a first bonding interface and a first plurality of interconnect layers arranged according to a first Manhattan wiring scheme. The three-dimensional integrated circuit stack also includes a second die including a second bonding interface and a second plurality of interconnect layers arranged according to a second Manhattan wiring scheme. The first die and the second die stacked with the first bonding interface coupled to the second bonding interface such that the first Manhattan wiring scheme and the second Manhattan wiring scheme are non-Manhattan with respect to each other.

Abstract: Aspects of the disclosure includes a transistor-under-test (TUT) to charge/discharge a capacitor; changing an oscillation state when a capacitor voltage crosses a threshold and turning OFF the TUT; discharging the capacitor using the TUT; commencing precharging the capacitor after detecting the capacitor reaches a transition voltage; commencing discharging the capacitor after a precharger time delay; sustaining a relaxation oscillator waveform, wherein the relaxation oscillator waveform is based on turning OFF/ON the TUT; and generating a digital representation of a TUT current associated with a relaxation oscillator period of the relaxation oscillator waveform. For example, a measurement tile includes a pulse generator to sustain the relaxation oscillator waveform with the relaxation oscillator period associated with an inverse TUT current; and a precharger charging a capacitor and the TUT charging/discharging the capacitor, wherein the relaxation oscillator waveform is based on turning OFF/ON the TUT in accordance with discharging and charging the capacitor.
