In the light of the constantly growing complexity of integrated systems comprising mechanical components, electronic hardware and embedded software there is an increasing demand regarding their safety, security and robustness. Consequently, new concepts, methods, tools and related processes are needed in the systems development associated with an increasing number of regulatory requirements across the key industries.
Today model-based simulation techniques are commonly used in system development in conjunction with hardware-in-the-loop (HIL) facilities for the verification and also validation of their nominal functional performance.
With the application of model-based simulation in safety, security and reliability assessments, i.e. the simulation of malfunctions in complex, safety-critical systems in conjunction with the application of failure analysis methodologies will have a significant beneficial impact on model-based development of complex systems, thus it will drastically shorten the integration and verification-phase and will directly support the relevant qualification and certification activities.
To optimally support this approach the key project of ROSAS is the development of a generic safety and security in-the-loop simulation test bench for the “in-the-loop” integration and verification of systems (“xIL”).
In combination with automated features the long-term objective is to provide the capability of performing design for certification at a maximum in flexibility for design adaptations.
Additional benefits from this approach are:
This applies in particular for embedded systems which are becoming the functional backbone in complex technical products. One of the key challenges lies in the twofold demonstration of the design assurance of systems by a) analyzing their nominal functioning and b) the effects in case of malfunctions. With the growing complexity of the applied hardware and software and their interactions the related development processes have to be adapted to enable the integration of innovative technology in safe, secure and reliable systems in compliance with the applicable regulations and standards.
Leading edge technology for innovative and competitive products requires an optimally tailored development processes framework considering:
