TTTech, the leading supplier of solutions in the field of time-triggered systems, and Esterel Technologies, the worldwide

leader of model-based design and verification tools for critical embedded systems, announce the availability of TTP-SCADElink and

SCADE TTA-Extension. This software interface tool is used for the seamless integration of TTTech's TTP-Tools and Esterel Technologies'

SCADE Suite. TTP-SCADElink is a powerful solution for the design of distributed control systems and software applications in more

electric aircraft systems. It is currently evaluated by many aircraft equipment suppliers for the next generation of complex

on-board systems.

"Thanks to the combination of TTP-Tools and SCADE, we have achieved an advanced project", says David Poiret, system engineer at

Messier-Bugatti. "The result is a partitioned, safe and fault-tolerant architecture that enables an optimized certification of software

application and middleware".

The SCADE TTA-Extension, delivered by Esterel Technologies, enables the modeling of a fault-tolerant, communication-based, distributed

system. The architecture, the functional behavior and the data exchange requirements are specified at SCADE model level to generate

the whole embedded distributed software.

TTP-SCADElink, provided by TTTech, enables the use of TTP-Tools for the automatic scheduling of communication and tasks. High-level

communication requirements, time budget and task schedule are automatically computed to generate the dedicated, time-triggered

middleware.

The TTP-Tools and SCADE Suite create a comprehensive development environment that enables cost-effective engineering, formal

verification and safe mapping on to the distributed hardware of complex integrated aircraft systems; importantly systems that are

certified to DO-178B up to level A. The complete qualification package compromises the SCADE KCG qualification kit and the TTTech

qualification data for software components and communication controller.
