A new low-power test compression scheme, called Dcompress, is proposed for launch-on-capture (LOC) transition fault testing by using a seed encoding design testability architecture, and application procedure. The scheme generates seeds all tests selecting primitive polynomial that encodes of compact set. software-defined linear feedback shift register SLFSR, to make the method conform current f...

One of the major challenges in testing a System-on-a-Chip (SOC) is dealing with the large test data size. To reduce the volume of test data, several efficient test data compression techniques have been recently proposed. In this paper, we propose hybrid test compression techniques that combine the Geometric-Primitives-Based compression technique with the frequency-directed run-length (FDR) and ...

A mini-corpus of twelve ‘calibrated’ binary-data files have been produced for systematic evaluation of compression algorithms (Available at http : //www.tcode.auckland.ac.nz/-mark/corpus). These are generated within the framework of a deterministic theory of string complexity [2]. Here the T-complexity of a string z (measured in taugs) is defined as CT(Q) = Ci logz(ki + 1): where the positive i...

Causality testing, the act of determining cause and effect from measurements, is widely used in physics, climatology, neuroscience, econometrics and other disciplines. As a result, a large number of causality testing methods based on various principles have been developed. Causal relationships in complex systems are typically accompanied by entropic exchanges which are encoded in patterns of dy...

Higher Circuit Densities in system-on-chip (SOC) designs have led to drastic increase in test data volume. Larger Test Data size demands not only higher memory requirements, but also an increase in testing time. Test Data Compression/Decompression addresses this problem by reducing the test data volume without affecting the overall system performance. This paper presented an algorithm, XMatchPr...

Sweating is an important mechanism for ensuring constant thermoregulation, but hyperhidrosis may be disturbing. We present five cases of hemifacial hyperhidrosis as a compensatory response to an/hypohidrosis caused by cervical disc herniation. All the patients complained of hemifacial hyperhidrosis, without anisocoria or blepharoptosis. Sweat function testing and thermography confirmed hyperhid...

A new scan architecture for both low power testing and test volume compression is proposed. For low power test requirements, only a subset of scan cells is loaded with test stimulus and captured with test responses by freezing the remaining scan cells according to the distribution of unspecified bits in the test cubes. In order to optimize the proposed process, a novel graph-based heuristic is ...

We present a new test response compression method called cumulative balance testing (CBT) that extends both balance testing and accumulator compression testing. CBT uses an accumulated balance signature, and it guarantees very high error coverage (over 99%) for various error models. We demonstrate that the single stuck-line (SSL) fault coverage of CBT for many of the ISCAS 85 combinational benc...
