Abstract
In industrial applications, the number of final products endowed with real-time automatic control systems that manage safety-critical situations has dramatically increased. Thus, it is of growing importance that the control system design flow encompasses also its translation into software code and its embedding into a hardware and software network. In this paper, a tool-supported approach to the formal analysis of real-time aspects in controller implementation is proposed. The analysis can ensure that some desired properties of the control loop are preserved in its implementation on a distributed architecture. Moreover, the tool provides as output information which can be used to approach straightforwardly some design problems, such as hardware sizing in the final implementation.
