Abstract
Systems and methods for testing electrical connections between a chip and external circuitry are discussed. In some embodiments, a chip may include an Input/Output (I/O) terminal and a test circuit coupled to the I/O terminal, wherein an oscillating frequency of the test circuit changes in response to an impedance change at the I/O terminal due to a connection failure or degradation.
