The quality of test for every core that is integrated on the chip is very important to the overall quality of the SoC. In this paper a method for evaluating the quality needs of an embedded core relative to the embedded environment is presented. Due to the partitioning of the test data and the increased stress in quality for individual designs the test application time is increasing. This paper presents the problems associated with test application time with SoCs.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

At the end of each time frame a pair of waveforms, one belonging to an aggressor node, and one depicting a victim node, is inspected. If the fault is captured, it will be simulated until it is either detected or the test vectors are exhausted. This fault detection method can require a prohibitive amount of computation time for a large sequential circuit with high number of possible fault pairs to be tested. With our simulation technique, introduced in this paper, these operations can be processed concurrently for many faults. The fault list dynamically adjusts itself during the simulation to accommodate fault injection and fault dropping. Experimental results on ISCAS'89 benchmark circuits show that a substantial improvement in CPU time, over a conventional method, is achieved with a trade-off in the amount of memory consumed.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

States for FSM testing are classified into valid test states and invalid test states. This method reduces the numbers of invalid test states and valid test states using a don't care input identification technique and a state compaction technique. The test length may be shortened by reducing the number of valid test states and additional test area is reduced by reducing the number of invalid test states. Experimental results for MCNC'91 FSM benchmarks and practical FSMs show that the proposed method reduces the test area by 13 to 77% and shortens the test lengths by 10 to 36%.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

First, for delay-fault test pattern sets of ISCAS89 benchmarks, this algorithm can cut down 37.5% or more test power than the simulation-based annealing algorithm. Second, because approaches which use the Hamming distance between two input test patterns, to optimize the test power, cannot reduce as much power for ISCAS85 benchmarks as expected, a novel optimization approach that uses the power of an ideal circuit without delay, to optimize the test power is presented. Experimental results demonstrate that our approach can cut down 70.8% more test power than present approaches. Third, the influence of undetermined test bits on test power optimization is studied by changing the number of undetermined bits in test patterns. Experimental results demonstrate that with the increase of undetermined test bits, the un-optimized test power markedly decreases.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

Although I/sub DDQ/ testing is known to be effective in detecting faults in CMOS circuits, the test time of I/sub DDQ/ testing is larger than that of logic testing. It is shown that the test time of I/sub DDQ/ test mostly depends on the switching current. To reduce the test time of I/sub DDQ/ testing, a procedure to arrange test vectors such that the switching current quickly disappears is proposed for combinational circuits. The procedure utilizes a unit delay model to estimate the time of the last transition of logic values from low to high in a circuit. Experimental results for benchmark circuits show the effectiveness of the procedure.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

We then investigate, for each type of trend, the field quality of software products developed by the corresponding software projects.
