Zusammenfassung:	A process for identifying the location of a break in a scan chain in real time as fail data is collected from a tester. Processing a test pattern before applying it on a tester provides a signature enabling a method for a tester to identify a scan cell which is stuck during the time the tester is operating on a device under test rather than accumulating voluminous test data sets for delayed offline analysis.
