    Abstract: A method and system for performing a self-test of power supply quality for an integrated circuit chip within an electronic system. The electronic system is subjected to a well-defined repetitive activity, such as by using an amplitude modulated system clock tree. With the repetitive activity causing current consumption within the chip, time-domain local power supply voltage (U(t)) is measured for a location on the chip. A set of time-domain measured voltage data (U(t)) is accumulated and transformed into the frequency domain to yield a local voltage profile (U(f)). The local voltage profile (U(f)) is compared with a reference voltage profile (U0(f)) to verify whether power supply quality at the chip location under test is adequate. Alternatively, a local impedance profile Z(f) evaluated from the local voltage profile (U(f)) may be compared to a reference impedance profile Z0(f).

The pad capacitance test circuit may be located on a die including the electronic circuit. The pad capacitance test circuit may reset a pad voltage of one or more of the pads to zero, and then couple the pad to a supply voltage through a pullup resistor for a time period. The final pad voltage at or near the end of the period of time may be measured. The pad capacitance may be determined from the measured value of the final pad voltage and known values of the supply voltage, the time period, and resistance of the pullup resistor.
