This paper aims at broadening the scope of hierarchical ATPG to the behavioral-level. The main problem is identified, namely the mismatch of timing models between the behavioral- and gate-levels. As a main contribution of this paper, a theoretical analysis of this problem led to the definition of a novel concept, that of dominated patterns, that captures the needed link between the levels. Some metrics are defined, taken from the software realm, that allow generation of test patterns at the behavioral-level. To validate the concept correctness, different ATPG systems are presented, and experimental results show an improvement in the test quality, thanks to the exploitation of behavioral-level information. 相似文献

The paper presents a life cycle assessment of a kenaf-fibre insulation board following the international standards of the ISO 14040 series. Each life-cycle step has been checked, from kenaf production and board manufacture by an Italian firm, to use and disposal. 相似文献

The paper expands on some specific aspects of personal communications via satellite, often–although not necessarily–envisaging extensive use of ‘small’ satellites, using orbits not necessarily coinciding with the geostationary one (36,000 km), but rather at 1000–11,000 km altitude. One key point to be borne in mind is the issue of internetworking between satellite and terrestrial systems. Network integration should be carefully implemented in order to comply with ITU future public land mobile telecommunication systems (FPLMTS) requirements, also accepted in the European Telecommunication Standards Institute (ETSI) universal mobile telecommunication systems (UMTS). In addition to some insight into the technology of small satellites and associated orbits, architectures and networking aspects of most relevant systems providing personal communication services (PCS) are addressed in some detail, and potential applications highlighted. Frequency spectrum allocation is addressed in the light of the 1992 World Administrative Radio Conference (WARC-92), taking into account also multiple access problems and regulatory issues such as Federal Communications Commission (FCC) licensing and spectrum sharing debates. Some remarks on critical technologies and cost conclude the paper. 相似文献

The aim of this paper is to present a general methodology for studying printed electromagnetic structures. Canonical microstrip structures can be described by means of a system of coupled integral equations, which can be easily transformed into a system of algebraic equations by using the Neumann series, namely a series of Bessel functions. Careful numerical analysis shows that, in order to obtain a reasonable accuracy of the fields and/or potential, small matrices are necessary. Static and dynamic cases are discussed. 相似文献

In this paper we present a study of graphene produced by chemical vapor deposition (CVD) under different conditions with the main emphasis on correlating the thermal and electrical properties with the degree of disorder. Graphene grown by CVD on Cu and Ni catalysts demonstrates the increasing extent of disorder at low deposition temperatures as revealed by the Raman peak ratio, IG/ID. We relate this ratio to the characteristic domain size, La, and investigate the electrical and thermal conductivity of graphene as a function of La. The electrical resistivity, ρ, measured on graphene samples transferred onto SiO2/Si substrates shows linear correlation with La(-1). The thermal conductivity, K, measured on the same graphene samples suspended on silicon pillars, on the other hand, appears to have a much weaker dependence on La, close to K~La1/3. It results in an apparent ρ~K3 correlation between them. Despite the progressively increasing structural disorder in graphene grown at lower temperatures, it shows remarkably high thermal conductivity (10(2)-10(3) W K(-1) m(-1)) and low electrical (10(3)-3×10(5) Ω) resistivities suitable for various applications. 相似文献
