Applying the composition filter model for runtime verification of multiple-language software

Abstract — Complex software, especially the embedded one, is composed of multiple collaborating subsystems that are possibly developed in multiple languages. To verify the behavior of such software, a run-time verification system must deal with multiple-language environments both in its specifications and in its generated runtime verification modules. In this paper, we present the E-Chaser runtime verification system, whose front-end provides language-independent specifications, and whose back-end provides an extendable toolset with new implementation languages. E-Chaser is built based on the Composition Filter Model and extends it with the notion of synchronization messages and synchronization filters to verify the synchronization properties of multiple subsystems. The first prototype of E-Chaser was successfully used to verify various properties
