Rigorous System Design deals with the formalization of the design of mixed hardware/software systems. It advocates rigorous system design as a coherent and accountable model-based process leading from requirements to correct implementations. It presents the current state of the art in system design, discusses its limitations and identifies possible avenues for overcoming them. A rigorous system design flow is defined as a formal accountable and iterative process composed of steps, and based on four principles: 1) separation of concerns; 2) component-based construction; 3) semantic coherency;...
