20080215940 | Methods and apparatus for estimating a position of a stuck-at defect in a scan chain of a device under test - As a scan pattern is shifted out of a scan chain, the scan pattern is evaluated in real-time for the existence of a logic condition. A reference to a portion of the scan pattern that is currently being evaluated is maintained. Upon identifying the existence of the logic condition when the reference has a predetermined relationship to a stored value, the stored value is overwritten using the reference. The stored value is then used to estimate the position of a stuck-at defect in the scan chain. | 09-04-2008 |
