摘要: An integrated circuit fault detection system. The system includes gate means associated with each functional input and output of the chip. are connected between terminals bonding pad controllable to allow chip operate in normal fashion using thereof pads therewith. also read test data into a terminal chip, write out drive from circuitry through off accept outside world transfer circuitry. results can then be analyzed determine if is functioning properly.
