20100229060 | Compression Based On Deterministic Vector Clustering Of Incompatible Test Cubes - The test data compression scheme is based on deterministic vector clustering. Test cubes that feature many similar specified bits are merged into a parent pattern in the presence of conflicts. The parent pattern along with a control pattern and incremental patterns representing conflicting bits are encoded efficiently. A tri-modal decompressor may be used to decompress the test data. | 09-09-2010 |

20120210181 | SELECTIVE PER-CYCLE MASKING OF SCAN CHAINS FOR SYSTEM LEVEL TEST - Built-in self-test techniques for integrated circuits that address the issue of unknown states. Some implementations use a specialized scan chain selector coupled to a time compactor. The presence of the specialized scan chain selector increases the efficiency in masking X states. Also disclosed are: (1) an architecture of a selector that works with multiple scan chains and time compactors, (2) a method for determining and encoding per cycle scan chain selection masks used subsequently to suppress X states, and (3) a method to handle an over-masking phenomenon. | 08-16-2012 |
