Reconfigurable cores support post-release updates which shortens time-to-market while extending circuits' lifespan. Reconfigurable cores can be provided as hard cores (ASIC) or soft cores (RTL). Soft reconfigurable cores outperform hard reconfigurable cores by preserving the ASIC synthesis flow, at the cost of lowering scalability but also exacerbating timing closure issues. This article tackles these two issues and introduces the ARGen generator that produces scalable soft reconfigurable cores. The architectural template relies on injecting flip-flops into the interconnect, to favor easy and accurate timing estimation. The cores are compliant with the academic standard for place and route environment, making ARGen a one stop shopping point for whoever needs exploitable soft reconfigurable cores.

The present paper describes the validation and the modeling capabilities of a new fully coupled floating wind turbine simulator based on DeepLines? software. A first validation, based on code comparison with NREL-FAST software, is presented and shows very good correlation on a rigidly founded 5MW wind turbine in various wind conditions despite the different modeling techniques and assumptions of the two softwares. This benchmark, in addition to the extensive validation on various offshore projects, makes us confident on DeepLines capabilities to assess founded and floating wind turbine behaviour in a complex offshore environment. Furthermore, some simulation results on jacket and floating founded wind turbines, defined in the frame of IEA OC4 project, are presented and highlight the versatility of our simulator to perform offshore and floating wind turbine optimal design.

From 28nm technology node and below, Optical Proximity Correction (OPC) needs to take into account light scattering effects from prior layers when bottom anti-reflective coating (BARC) is not used, which is typical for implant layers. In this paper, we implement a sub-layer aware simulation method into a verification tool for Optical Rule Check (ORC) that is used on full 28nm test chip. The sub-layer aware verification can predict defects that are missed by standard ORC. SEM-CD review and defectivity analysis were used to confirm the validity of the sub-layer aware model on wafer.

We propose a new physical simulation tool of GR and diffusion noise in semiconductor devices by introducing distributed Langevin noise sources into the transmission line equivalent circuit model of the fundamental transport equations, first proposed by Sah. The whole circuit is then introduced into a circuit simulator in order to perform full noise simulations of semiconductor devices. Commercially available simulators present considerable advantages in performing accurate DC, AC and transient simulations of semiconductor devices, including many fundamental and parasitic effects which are not generally taken into account in house-made simulators. A significant feature of this method is the integration of the physics-based device simulator and an electrical circuit simulator into a combined simulation environment. An extension of this model to homo-junctions and hetero-junctions is in progress as the simulation of cyclo-stationary noise sources with non-linear circuit simulation.

We propose a robust solution to accurately simulate the trap assisted GR noise in real-life semiconductor devices at low as well as high injection levels. The powerful postprocessing tool developed on the mathematical SCILAB software package is the Langevin method associated to Green's functions responses of the device. It allows performing accurately noise simulations of semiconductor devices. Our numerical simulator of trapping noise in semiconductor devices is coupled with the output data of one of the simulator available in the public domain, namely Sentaurus fron Synopsys. Commercially available simulator present considerable advantages in performing accurate DC, AC and transient simulations of semiconductor devices, including many fundamental and parasitic effects which are not generally taken into account in house-made simulators.

This paper presents a new method for computing the Feature-adapted Radon and Beamlet transforms [1] in a fast and accurate way. These two transforms can be used for detecting features running along lines or piecewise constant curves. The main contribution of this paper is to unify the Fast Slant Stack method, introduced in [2], with linear filtering technique in order to define what we call the Feature-adapted Fast Slant Stack. If the desired feature is chosen to belong to the class of steerable filters, our method can be achieved in O(N log(N)), where N=n{sup}2 is the number of pixels. This new method leads to an efficient implementation of both Feature-adapted Radon and Beamlet transforms, that outperforms our previous works [1]. Our method has been developed in the context of biological imaging to detect image features lying along curves like edges or ridges as well as any kind of features that can be designed by a priori knowledge.

The fibre-optic telecommunication market continues to evolve dramatically. This presentation points out the latest economical evolutions in this moving market and shows the key roles that optical actuators such as MEMS and MOEMS will play in a near future (specially for key systems such as Optical Cross-Connects). This paper describes the current European state-of-the-art into the technologies for the manufacture of all-optical wavelength-handling components (routing, splitting, multiplexing, add-dropping, attenuating ...) and the position of Micro Technologies in terms of: 1. European industrial offer 2. R&D developments 3. Technical performances
