Abstract: Aspects of the disclosure provide a method for tuning delay. The method includes driving, during a calibration stage, at least one test signal from an integrated circuit onto a plurality of outside transmission lines that are coupled to the integrated circuit, measuring a timing of the at least one test signal transmitted and reflected over the plurality of outside transmission lines, and selectively delaying, using units disposed within the integrated circuit, signals subsequently transmitted over the plurality of outside transmission lines based on the timing of the at least one test signal, in order to align transmission times of the subsequently transmitted signals.

Abstract: An integrated circuit includes an operational circuit module receiving a supply voltage from a voltage regulator external to the integrated circuit, and an adaptive voltage scaling module to adjust the supply voltage based on performance characteristics of the operational circuit module.
