Abstract
A pad capacitance test circuit may be coupled to one or more pads of an electronic circuit, such as a processor. 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.
