Abstract
A packaged integrated circuit (IC) chip that provides input/output (I/O) signal fail safe verification is disclosed. The packaged IC chip includes a first processing unit, a first control peripheral coupled to receive a first processed signal from the processing unit and to provide an output signal, and compare logic. The compare logic is coupled to receive the output signal and a comparison signal, to compare the output signal and the comparison signal, and to provide an error signal responsive to a difference between the output signal and the comparison signal.
