IEEE Standard for Ubiquitous Green Community Control Network Protocol

This compaction effect is significant for some cases Since, to our knowledge, there is no prior work on test set relaxation for traditional -detect test IEEE Standard for Ubiquitous Green Community Control Network Protocol sets we have implemented a simple test relaxation technique in order to demonstrate the effectiveness of the proposed method. Specifically, this method is a brute-force method in which each test is fault simulated and only the detected faults that have not been covered times are used to generate IEEE Standard for Ubiquitous Green Community Control Network Protocol a new test, with fewer specified bits, to replace the one from the original test set.

Consequently, fault dropping is performed after each test replacement. In this manner, each considered test to be relaxed will IEEE Standard for Ubiquitous Green Community Control Network Protocol no longer have to target a fault if it has already been detected times. Table lists the obtained results. The initial test sets are the same as those used for the experiment in Table list the specified to total bits ratio for the brute-force and the proposed approach, respectively. In all cases the proposed methodology is more effective in decreasing the number of specified bits.

This demonstrates that the optimization goal targeted in the proposed approach helps in finding better sets of tests to target a fault such that the number of specified bits is reduced, than a straightforward approach that selects these test sets in a brute-force manner first tests in the test set that detect the fault. The comparison in carried out with a brute force technique for test set relaxation. IEEE Standard for Ubiquitous Green Community Control Network Protocol Since we acknowledge that commercial tools can also produce -detect test sets with a number of don’t cares, in the obtained results are compared to detect test sets obtained by a commercial tool. Note that, the commercial tool does not apply any relaxation process, hence, the comparison may be a inequitable. Moreover, the test sets obtained by the specific commercial tool do not have fault coverage, because of the internal test set compaction process. For these two reasons, we have slightly modified our technique in order to provide, as much as possible, a comparable comparison. Specifically, we have relaxed the restriction for detecting all times appropriately, so that the compared test sets achieve very similar -detect fault coverage.

This fault coverage is reported in of This metric can some times be misleading since it does not distinguish between a fault detected a lot of times fewer than and one detected times . Definition 1 provides a better metric. IEEE Standard for Ubiquitous Green Community Control Network Protocol Here, we upper bound with in order to avoid counting coincidental detections. Observe that the corresponding columns in the table have very similar values. report the test set size and the percentage of don’t care bits for the test sets obtained by the commercial toolreport the test set size and the percentage of don’t care bits for the test sets obtained by the proposed method, after the modification discussed in this paragraph. Due to space limitations we show only larger circuits here which are more indicative than smaller circuits. Observe, that in all cases the percentage of don’t cares are higher for the proposed methodology even though the number of tests in the set are always smaller. In the cases of the number of test sets are significantly smaller, yet the percentage of don’t cares are still higher. These results will give much smaller actual number of specified bits in the test sets obtained
