Modelling and verification of an atomic action protocol implemented in Ada

Ada 95 is an expresses concurrent programming language with which it is possible to build complex multi-tasking applications. Much of the complexity of these applications stems from the interactions between the tasks. This paper argues that Petri nets offer a promising, tool-supported, technique for checking the logical correctness of the tasking algorithms. The paper illustrates the effectiveness of this approach by showing the correctness of …
