Item Speed-up of high accuracy analog test stimulus optimization(1999) Khouas, Abdelhakim; Derieux, AnneAnalog integrated circuit testing and diagnosis is a very challenging problem. The inaccuracy of measurements, the infinite domain of possible values and the parameter deviations are among the major difficulties. During the process of optimizing production tests, Monte Carlo simulation is often needed due to parameter variations, but because of its...Item Methodology for Fast and Accurate Analog Production Test(1999) Khouas, Abdelhakim; Derieux, AnneThis paper describes a new technique to reduce the number of simulations required during analog fault simulation. The method takes into account process parameter variations and aims to reduce the number of the computational expensive Monte Carlo simulations often required during analog fault simulation.

The inaccuracy of measurements, the innite domain of possible values and the parameter deviations are among the major diOEculties. During the process of optimizing production tests, Monte Carlo simulation is often needed due to parameter variations, but because of its expensive computational cost, it becomes the bottleneck of such a process. This paper describes a new technique to reduce the number of simulations required during analog fault simulation. This leads to the optimization of production tests subjected to parameter variations. In section I a review of the state of the art is presented, section II introduces the algorithm and describes the methodology of our approach. The results on CMOS 2-stage opamp and conclusions are given in sections III and IVItem Seminumerical technique for the analysis of integrated semiconductor devices(1994) Dehmas, Mokrane; Zitouni, Abdelkader; Bourdoucen, H.Item Quasi-static MoL-based approach for the analysis of multilayer transmission line structures(John Wiley & Sons, 1997) Zitouni, Abdelkader; Bourdoucen, H.; Nait Djoudi, T.Item Calculation of liquid-phase mass transfer coefficient on directional-jet trays with longitudinal partitions(Springer, 1993) Auashria, S.Item Vortex dynamics studied over a wide range of time scale in Bi-2212 Crystals(1995) Goupil, Ch.; Ruyter, A.; Provost, J.; Aouaroun, T.; Simon, Ch.Item Study of vortex motion in a sintered high Tc superconductor by a vibrating reed technique(1996) Richard, L.; Woirgard, J.; Aouaroun, T.; Rabier, J.Using a vibrating reed technique in a subresonant excitation mode, dissipation mechanisms have been studied in sintered YBa2Cu307-, superconductors with different grain sizes. Experimental results are interpreted within the critical state model. Results deduced from vibrating reed technique are compared with ac susceptibility measurements. It is shown that both techniques give consistent resultsItem One-dimensional brownian-motion model for transport measurements in high-temperature superconductors(1996) Goupil, Ch.; Aouaroun, T.; Thopart, D.; Hamet, J. F.; Simon, Ch.Using a one-dimensional model of Brownian motion of vortices over pinning wells, we derive a current-voltage equation assuming a distribution of the effective pinning length. The model describes linear and nonlinear regimes of the E(J) curves in a single-particle description. Thermally activated flux flow and flux flow define the two limits of the dissipative process, respectively, at very low and high current. The pinning relief is described by pinning well depth and pinning well gradient, respectively, which can be checked by resistive and current-voltage measurements. The model is then applied to a YBa2Cu3O7−δ thin film. It provides a phenomenological model of the dissipation induced by transport currentItem Anisotropic resistivity measurements by a multi-terminal transport method(IOP Publishing, 1997) Aouaroun, T.; Hardy, V.; Goupil, Ch.; Warmont, F.; Villard, G.; Simon, Ch.
