Summary: | A chip includes one or more function input pads, a sequence generation circuit, one or more logic circuits, one or more scan chains, a selection circuit, and one or more sequence output pads. The function input pad is configured to receive a function sequence. The sequence generation circuit is configured to generate a diagnosis sequence. The logic circuit includes a plurality of logic gates, for responding to the function sequence and outputting one or more logic results. When enabled by the selection circuit, the scan chain outputs a response result in response to the logic result or a diagnosis result in response to the diagnosis sequence. The sequence output pad receives the diagnosis result when the scan chain responds to the diagnosis sequence. |
