Innovation

The objective of the RAPID SIMPLEXE (SImulation des SystèMes Complexes) project is to push back the limitations of current simulation software by proposing innovative methods to solve ElectroMagnetic problems in complex civil and military systems. Two strategic axes are examined to optimize the compromise between precision and computational resources in the analysis of complex systems: Decompose the system into sub-elements that are simpler to represent; Use an efficient simulation method for each element.

is a European project aimed at building and demonstrating a commercial HPC cloud to enable European industry, and more particularly SMEs, to benefit from the efficiency and competitive advantage inherent in the use of simulation.

The project is funded by the European Commission through the 7th Framework Programme and is part of the I4MS initiative.
In this project, Nexio was the lead partner of Experiment 513: “Antenna and radar signature simulation in cloud mode”. An HPC simulation offer in Cloud mode on Bull’s ExtremeFactory platform has been put in place. Lun’tech was able to use it to simulate the SER of reflectors based on Luneberg lenses and trihedral reflectors.

Partners: Lun’tech, Bull, Genci.

Start: 10/2014 – Duration: 18 months

The aim of the project is to build a systems co-design methodology, common from chip to equipment, in order to accelerate the development of electronic systems while guaranteeing reliability and security.

The different axes of the project are :

manage the electrical characteristics observed by passive components and active devices, in order to determine their destruction mechanism and electrical characteristics.
understand and map the propagation paths of EFT disturbances inside an electronic chip.
provide guidelines and internal IC models to create more robust integrated circuits and develop safer applications.
propose new characterization and injection techniques to understand failure mechanisms at the IC board level.
propose to standards committees (ESDA, IEC) measurement methods and behavioral modeling methodology at component and system level.

NEXIO is a member of the steering committee of this project which is carried by LAAS-CNRS.

Partners: LAAS-CNRS, NXP, VALEO.

The LOCRAY project is a major step towards the emergence of an ecosystem around near-field emission measurements by adding the link between investigative (near-field) and qualifying (normalized) measurements.
The partners are world-renowned players in the field of EMC at the component, equipment and system level, and are historically involved in the development of near-field measurements.

Objectives:
From the design phase to production, the near field with its visual approach is a technology used by non specialists in electromagnetism to :

technological choices,
routing optimization,
the search for the sources of disturbances,
obsolescence management,
production control.

The 2 major axes of innovation are :
1) Predicting qualification measures with post-processing of data
2) Increase the refinement of the measurement to make it more accurate and usable in the simulation

(Simulation of Emission and Immunity of Electronic Systems and Modules) The objectives of this project are to define new methodologies for the analysis of EMC during a modification of a component, board or equipment. This project must :

help to develop the design by “Virtual Prototyping” of embedded electronics to reduce the design and development time of prototypes,
Reduce the number of equipment and system EMC requalification tests, and thus the time and cost of these tests,
reinforce the “Virtual Test” for the validation of these electronic modules, by defining standardized setup models,
propose standards for electronic component/board/equipment models and their associated extraction methods.

The objective of this project is to propose a breakthrough technology for electromagnetic simulation and modeling by combining 2 original and innovative methods from R&D projects, namely KRON and ACA. The results of this project will be included in the CAPITOLE-EM software environment. The 4 target applications are :

indirect effects of lightning on civil buildings and aircraft,
Simulation and measurement of Radar Equivalent Surfaces (stealth targets, electromagnetic shields),
the radiation of the antennas and their coupling in near field,
and the evaluation of the internal environment of aircraft cabin type resonant cavities or mode stirred reverberation chamber (MBRC).

NEXIO is the project leader.

As part of the AEROSAT 2012 program and to take into account the new all-electric architecture implemented by EADS, the objective of this project is to design a generic module to interface current equipment by making it operable/reusable with future digital networks. To be generic, the SBA module will have to recognize different buses (AFDX, ARINC, CAN) and adapt to different equipment (different sockets, different connections …). NEXIO brings here its EMC/Aeronautical Lightning expertise in the design and validation phases.
