Abstract
An integrated circuitincludes a plurality of circuit blockseach having an associated serial scan chain loopwhich extends from a converter, to the circuit blockin question and then back to the converter. Multiplexing circuitryassociated with each serial scan chain loopis used to either include that serial scan chain loopin a combined serial scan chain or to bypass that serial scan chain loop. The circuit blocksmay be bypassed in this way if they are defective or if they are powered-down.
