Abstract

In this paper, we present ÁTAME, an assertion-based program specialization tool for the multi-paradigm language Maude. The program specializer ÁTAME takes as input a set \(\mathcal{A}\) of system assertions that model the expected program behavior plus a Maude program \(\mathcal{R}\) to be specialized that might violate some of the assertions in \(\mathcal{A}\). The outcome of the tool is a safe program refinement \(\mathcal{R}'\) of \(\mathcal{R}\) in which every computation is a good run, i.e., it satisfies the assertions in \(\mathcal{A}\). The specialization technique encoded in Open image in new window is fully automatic and ensures that no good run of \(\mathcal{R}\) is removed from \(\mathcal{R}'\), while the number of bad runs is reduced to zero. We demonstrate the tool capabilities by specializing an overly general nondeterministic dam controller to fulfill a safety policy given by a set of system assertions.
