Safety LTL properties are ubiquitous in the verification of safety critical systems. There is already evidence that translating safety properties into DFA rather than Büchi automata results in faster verification times. Conventional translation strategies can in some cases use unnecessarily large amounts of resources. We develop a symbolic adaptation of the active learning algorithm tailored to efficiently translate safety LTL properties into symbolic DFA. We demonstrate how an inductive inference procedure can be used to provide additional input to the algorithm that greatly improves performance for certain important families of properties. For completeness, we also provide an outline and examples of how such a procedure can be implemented. Finally, we compare with state of the art LTL translators and provide experimental evidence where our approach significantly outperforms conventional translation strategies.
