Integrated circuits (ICs) are provided. A representative IC includes a
first pad electrically communicating with at least a portion of the IC. The first
pad includes a first driver and a first receiver, with the first driver being configured
to provide a first pad output signal to a component external to the IC, and the
first receiver being configured to receive a first pad input signal from a component
external to the IC. The first receiver also is configured to provide, to a component
internal to the IC, a first receiver digital output signal in response to the first
pad input signal. A first test circuit also is provided that is internal to the
IC. The first test circuit is adapted to provide information corresponding to the
driver tristate leakage current of the first pad. Methods, computer-readable media,
systems and other ICs also are provided.
