  • Testable IC having analog and digital circuits
    Patent number: 6389567
    Abstract: The invention relates to an integrated circuit with at least an analog and a digital circuit that are interconnected by a signal path. In order to enable separate testing of the circuits, for example in accordance with the macro test approach, in the signal path a special seam circuit (200) is inserted. The seam circuit (200) is essentially a feedback loop (214) having a scannable flip-flop (210) and a multiplexer (220). The flip-flop (210) feeds a first input of the multiplexer (220), whereas a second input of the multiplexer (220) establishes an input (230) of the seam circuit (200). An output of the feedback loop (214) establishes an output of the seam circuit (200).
