However the sensitivity of IDDQ testing deteriorates significantly with technology scaling as intrinsic leakage of CMOS circuits increases. In this paper, we use a design technique for a high-performance cache, which greatly improves leakage current and hence the IDDQ testability of the cache with technology scaling. We utilize the concept of gated-ground (NMOS transistor inserted between ground line and SRAM cell) to achieve reduction in leakage energy due to the stacking effect of the transistor without significantly affecting performance. Simulation results for a 64 K cache show 20% average improvement in IDDQ sensitivity for TSMC 0.25 /spl mu/m technology, while the improvement is more than 1000% for the 70 nm predictive technology model.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

These algorithms, however, have limited practical application since they are based on generic memory operations (writes and reads) rather than the DRAM specific operations (activation, precharge, etc.). This paper extends the approximation algorithms by incorporating the DRAM specific operations, making them directly applicable in practice. In addition, based on the new extended method, the paper shows results of a fault analysis study of cell defects using electrical simulation.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

Multiple seeds are produced by the TPG itself to deal with hard-to-detect faults, and this function is achieved without using a ROM to store the seeds. A reseeding logic is incorporated in the TPG, which loads new seeds into the LFSR whenever specific states are reached. In this way, useless test vectors are skipped and thus the test application time can be greatly reduced. We experiment the design methodology by applying it to some MCNC benchmark circuits, and the results show that TPGs designed with this technique require much less hardware overhead than the previous known reseeding techniques.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

Unlike most previous methods that only aim at identifying the faulty signals, our goal is to further narrow down the faults to a few suspected segments.

The algorithm is based on our previous inject-and-evaluate paradigm using symbolic simulation. It is fast and accurate.
