Types Of Faults

A recent work showed that it is possible to transform a single-cycle test for stuck-at faults into a launch-on-shift (LOS) test that is guaranteed to detect the same stuck-at faults without any logic or fault simulation. The LOS test also detects transition faults. This was used for obtaining a compact LOS test set that detects both types of faults. In the scenario where LOS tests are used for both stuck-at and transition faults, this article observes that, under certain conditions, the detection of a stuck-at fault guarantees the detection of a corresponding transition fault. This implies that the two faults are equivalent under LOS tests. Equivalence can be used for reducing the set of target faults for test generation and test compaction. The article develops this notion of equivalence under LOS tests with equal primary input vectors and provides an efficient procedure for identifying it. It presents experimental results to demonstrate that such equivalences exist in benchmark circuits, and shows an unexpected effect on a test compaction procedure.

Mechanics properties of lime- fly ash stabilized soil are investigated. First, the chemical composition of fly ash are analyzed by spectral analysis test. Compaction experiments of all mix proportion projects are carried out in different water conditions to obtain the optimum water contents. Then the optimum mix proportion is obtained by the unconfined compressive strength and the compression rebound modulus test. Finally, the pavement structures design for a highway of lime- fly ash stabilized soil road sub-base is done. By the comparison, a conclusion can be drawn that lime-fly ash stabilized soil is suitable for flexible pavement or semi-rigid pavement because of its good strength and rigidity which can effectively reduce thickness of the lower pavement and basic deflection.
