This work presents probabilistic methods for testability analysis at RTL and their use to evaluate the sensitivity of a digital circuit to Single Event Upsets (SEUs). A new probabilistic testability metric is proposed, in order to evaluate if the possible changes caused by SEUs are ignored or propagated by the dynamic behavior of the circuit. The new(More)
Validation of RTL descriptions remains one of the principal bottlenecks in the circuit design process. Random simulation based methods for functional validation suffer from fundamental limitations and may be inappropriate or too expensive. In fact, for some circuits, a large number of vectors is required in order to make the circuit reach hard to test(More)
High quality Built-In Self Test (BIST) needs to efficiently tackle the coverage of random-pattern-resistant (r.p.r) defects. Several techniques have been proposed to cover r.p.r faults at logic level, namely, weighted pseudo-random and mixed-mode. In mixed-mode test pattern generation (TPG) techniques, deterministic tests are added to pseudo-random vectors(More)
The asymmetric unit of the title compound, C(3)H(4)N(4)O(2)·0.5H(2)O, comprises two whole mol-ecules of 5-amino-1H-1,2,4-triazole-3-carb-oxy-lic acid in its zwitterionic form (proton transfer occurs from the carb-oxy-lic acid group to the N hetero-atom at position 1), plus one water mol-ecule of crystallization. The organic moieties are disposed into(More)
The high-valent oxo-molybdenum(VI) and -rhenium(VII) and -(V) derivatives MoO2Cl2, ReCH3O3 (MTO) and ReIO2(PPh3)2 catalyze the selective hydrogenation of alkynes to alkenes at 80 degrees C under 40 atm of pressure. The reduction of sulfoxides to sulfides has also been performed by oxo-rhenium and -molybdenum complexes using hydrogen as a reducing agent.(More)
During forest fire fights, firefighters are exposed to several pollutants at different concentrations, which can induce critical health problems. This study main goal is to estimate firefighters' pollutants inhalation when in operational scenarios by combining environmental and physiological information. Both exposures to CO (carbon monoxide) and(More)
New product development, based on SOC (System on a Chip) and IP (Intellectual Property) cores, requires, as much as possible, design and test UHXVH [1]. High design productivity drives the need for test preparation to be carried out as early as possible in the design flow, thus at RTL (Register Transfer Level) [2]. However, RT-level test patterns are not(More)
A rapid, mild and high-yield microwave synthesis of 1D isotypical [Ln(H4bmt)(H5bmt)(H2O)2]·3H2O coordination polymers is presented. The La(3+)-based material is highly active as a heterogeneous catalyst in the methanolysis of styrene oxide at nearly room temperature. Eu(3+)- and Tb(3+)-doped materials are very effective UV-to-visible light converters.
The title compound, [Mo(2)(C(5)H(10)NS(2))(2)O(4)]·C(4)H(8)O, can be readily prepared in tetra-hydro-furan (THF) by an oxidation reaction between the Mo(IV) precursor [MoO(S(2)CNEt(2))(2)] with [ReMeO(3)]. The compound is an axially symmetric Mo(V) dimer (2 symmetry), in which the metal atoms exhibit a distorted square-pyramidal coordination environment. A(More)
