Giannotti F., Latella D. Gate splitting in lotos specifications using abstract interpretation. Internal note CNUCE-B4-92-013, 1992.
In this paper the technique for an efficient solution to the problem of gate splitting in LOTOS specifications is presented. The transformation problem is part of a design methodology based on the specification language LOTOS. The problem is formally defined. The technique is based on Abstract Interpretatio which is used for approximating the sets of possible values which LOTOS value expressions can evaluate to. The originality od the proposed approach stems from the fact that the abstract domain as well as abstract functions are generated automatically from the LOTOS specification to be transformed. The abstract interpretation as well as the transformation are proved correct.
