The present invention concerns a method and a tool for designing and validating a data flow system comprising a set of software and/or hardware actors (a, a) interconnected with each other by unidirectional communication channels (c, c), the tool comprising: &#x2014;a modelling interface () configured to generate an instance of the system by specifying, in a formal manner, a real-time and reconfigurable data flow, the reconfiguration of the data flow being carried out dynamically by propagating reconfiguration data from one actor to another through the communication channels, &#x2014;an analysis module () configured to prove a predetermined set of behavioral properties of the system by means of a static analysis of the instance, &#x2014;a refinement interface () designed to allocate resources to the instance, thus establishing a configured instance, the allocation of resources being carried out in such a way that an implementation of the system complies with the configured instance, and &#x2014;a conformity test module () configured to verify the conformity of the behaviour of an implementation of the system with respect to the configured instance.
