Description
Summary:The approach proposed in this paper introduces a hardware/software co-design framework for developing complex embedded systems. The method relies on formal proof of system properties at every phase of the co-design cycle. The key concept is the combined use of UML and the B language for system modeling and design, and the seamless transition from UML specifications to system descriptions in B. The final system prototype emerges from correct-by-construction subsystems described in the B language; the hardware components are translated in VHDL/SystemC, while for the software components C/C++ is used. The outcome is a formally proven correct system implementation. The efficiency of the proposed method is exhibited through the design of a case study from the telecommunication domain.
