Design of Embedded and Cyber-physical Systems

Prof. Dr.-Ing. Rolf Ernst

CPA (compositional performance analysis) is an approach to formal performance analysis of large embedded systems that has been developed at IDA in many projects over more than 10 years. CPA has been commercialized as SymTA/S by the IDA spin-off, Symtavision. SymTA/S is a comprehensive Software-Toolbox for formal performance analysis and optimization of embedded systems. It is used in regular design processes throughout the international automotive industry and has been applied in other domains, such as avionics. Research at IDA continues with new models and analysis techniques using the research tool pyCPA.

Many related projects with industry are executed by the TTZ "Embedded Systems" of the TU Braunschweig innovation center iTUBS

• UNICARagil (Disruptive modular architecture for agile, autonomous vehicle concepts)
  Modelling and analysis of a service oriented software architecture according to hard safety and real-time requirements. Concepts for the deterministic realization of end-to-end latencies focusing on network communication.
  Project research staff (IDA): Jonas Peeck, Kai Björn Gemlau
  The Project UNICARagil is a collaboration of 7 Universities, 16 chairs and 6 industrial partners
  Funding: Bundesministerium für Bildung und Forschung (BmBF)
   
• AUTOTECH.agil („Architektur und Technologien zur Orchestrierung von automobiltechnischer Agilität - AUTOtech.agil“)
  Open software and hardware architecture for the vehicles of the future
  IDA is responsible for an extension of the timed software paradigm "Logical Execution Time" (LET) for software components to a "System-Level LET" for programming and combining large software systems of an automated vehicle.
  Project research staff (IDA): Kai Björn Gemlau, Sebastian Abel
  Academic partners are IFR and the RWTH. Industrial Partners of the IDA research are Mercedes-Benz, Vitesco, and Vector Informatik
