An approach to test optimization in switched-capacitor systems based on fault simulation at switch-level is presented in this paper. The advantage of fault simulation at this granularity level is that it facilitates test integration as early as possible in the design of these systems. Due to their mixed-signal nature, both catastrophic and parametric faults must indeed be considered for test op...

The basic idea for the development of this topic is to provide safety not only hospital but also sensitive areas like ICU’s, government offices. Automatic changeover single-phase load an electrical control panel that can give uninterrupted power supply under fault conditions any one phases in system. It capable transfer from main auxiliary during fault. This paper presents a prototype automatic...

In this paper, we present a fast and efficient algorithm for BISTing datapaths described at the Register Transfer (RT) level. This algorithm is parameterized by user defined tuning factors allowing tradeoffs between fault coverage, area overhead and test application time. This algorithm is also generic i.e. independent of the test pattern generators and compactors types.

Vanishree et.al proposed a novel unconditionally oblivious polynomial evaluation protocol and they claimed that can fulfill both sender and receiver’s security. Here, this protocol is cryptanalyzed. We find that it has a fatal fault which cannot implement the receiver’s security at all and show the detail analyzing process. Keywords oblivious polynomial evaluation, oblivious transfer, multi-par...

The semantics of HDL descriptions influences all facets of VLSI design such as synthesis, test, verification, logic simulation and fault simulation. In this paper formal semantics of the intermediate language TREEMOLA, used in the MIMOLA hardware design system MSS, is presented. In particular semantics of module declarations, described at the Register Transfer Level by the CHDL MIMOLA, is defined.

The reliability of Very Large Scale Integration (VLSI) circuits has become increasingly susceptible to transient faults induced by environmental noise with the scaling of technology. Some commonly used fault tolerance strategies require statistical methods to accurately estimate the fault rate in different parts of the logic circuit, and Monte Carlo (MC) simulation is often applied to complete ...

[1] The principal limitations of interferometric synthetic aperture radar (InSAR) to measure subtle, long‐wavelength deformation are uncertainties associated with the satellite orbits. We propose a method to remove orbital phase errors from the InSAR data by integrating InSAR and continuous GPS time series. We model the along‐track variation of the baseline errors as second‐order polynomials an...

In the condition monitoring of roller bearings, the measured signals are often compounded due to the unknown multi-vibration sources and complex transfer paths. Moreover, the sensors are limited in particular locations and numbers. Thus, this is a problem of underdetermined blind source separation for the vibration sources estimation, which makes it difficult to extract fault features exactly b...

We treat a fault as an array of asperities with a prescribed statistical distribution of strengths. When an asperity fails, the stress on the failed asperity is transferred to one or more adjacent asperities. For a linear array the stress is transferred to a single adjacent asperity and for a two-dimensional array to three adjacent asperities. Using a renormalization group (RG) method, we inves...
