ITTAP is a testability analysis program developed at the ITT-LSI technology center. In this paper we describe a testability measure for the test length and discuss the use of the selective trace concept for testability calculations. It is shown that ITTAP provides an order of magnitude improvement in run time over existing programs like SCOAP.
A new fault model (weak-0 and weak-1 faults) is presented to represent defects in CMOS circuits which may cause degradation of voltage levels without affecting logic values. It is shown that such faults can be effectively detected by IDDQ measurements. A hierarchical methodology is presented for selecting a small number of test vectors for detecting weak(More)
Success of endodontic treatment depends on the proper identi-fication of all the canals, thorough chemomechanical preparation followed by three-dimensional obturation with hermetic seal. Failure of any of these steps may occur due to unusual tooth morphology. Usually mandibular molars have two roots with three canals but in few teeth, the number of roots(More)
BACKGROUND AND OBJECTIVES To study the effect Achyranthes aspera, 0.2% aqueous chlorhexidine gluconate and Punica granatum oral rinse on salivary Streptococcus mutans count in children. MATERIALS AND METHODS A total of 60 children of 8 to 12 years of age were randomly allocated into 3 groups. Group A was given 0.2% chlorhexidine mouthwash, group B was(More)
