Abstract
A semiconductor integrated circuit (IC) comprising a time-to-digital converter (TDC) configured to measure an input-to-output delay of an I/O buffer of a pad the IC, the measured delay reflecting a connection impedance of the pad. A circuit in the IC, or a computer in communication with the IC, determines electrical connection integrity of the pad based on the measured delay of the I/O buffer.
