1. Introduction Logic Built-In Self-Test (BIST) schemes based on STUMPS structure use on-chip circuitry to generate test stimuli and analyze test responses, with little or no help from an ATE. The STUMPS (Self-Test Using a MISR and Parallel Shift register sequence generator) structure applies pseudo-random patterns generated by a PRPG (Pseudo-Random Pattern Generator) to a full-scan circuit in ...

Built-in self-test (BIST) is an attractive approach to detect delay faults because of its inherent support for at-speed test. Deterministic logic BIST (DLBIST) is a technique that has been successfully applied to stuck-at fault testing. As delay faults have lower random pattern testability than stuck-at faults, the need for DLBIST schemes has increased. However, an extension to delay fault test...

This paper deals with Hybrid multisite testing of VLSI chips by utilizing automatic test equipment (ATE) in connection with built-in self-test (BIST). The performance of a multisite testing process is analyzed using device-under-test (DUT) parameters (such as yield and average number of faults per DUT) as well as test process features (such as number of channels, coverage and touchdown time for...

We present the first delay-fault testing approach for Field Programmable Gate Arrays (FPGAs), applicable for on-line testing as well as for off-line manufacturing and system-level testing. Our approach is based on Built-In Self-Test (BIST), it is comprehensive, and does not require expensive external test equipment (ATE). We have successfully implemented this BIST approach for delay-fault testi...

original article     the aim of this study was to design and build a software for noise propagation prediction (indoor and from indoor to outdoor spaces) which is being commonly used in industry.  in this regard, firstly a mathematical complex model was created based on existing relationships about noise propagation in indoor spaces and transmission through the walls and propagation in outdoor ...

By using the Euler-Maclaurin’s summation formula and the weight coefficient, a pair of new inequalities is given, which is a decomposition of Hilbert’s inequality. The equivalent forms and the extended inequalities with a pair of conjugate exponents are built.

modern world faces a multitude of challenges regarding displacement including high fuel consumption, air pollution, congestion in streets, decrease in physical activities, insecurity of passers-by etc. most of which result from dependence on automobiles and the vehicle-stricken urban forms. planners and public health officials are turning to land planning and urban design for help in reducing a...

Formant trajectories of five American English diphthongs embedded in the target words BAIT (/ei/), BITE (/ai/), POUT (/au/), BOAT (/Ou/), BOYS (/oi/) are investigated in the F1-F2 space as a function of age and gender. Age range considered is from 5 to 18 years. In this report, the focus is given to the differences in position between the start/end points of diphthongs and nine monophthons. Ave...
