Abstract

We describe a formal tool based on a symbolic semantics for Full LOTOS, where speci cations without restrictions in their data types can be executed. The re ective feature of rewriting logic and the metalanguage capabilities of Maude make it possible to implement the whole tool in the same semantic framework, and have allowed us to implement the LOTOS operational semantics, to integrate it with ACT ONE speci cations, and to build an entire environment with parsing, pretty printing, and input/output processing of LOTOS speci cations. Our aim has been to implement a formal tool that can be used by everyone without knowledge of the concrete implementation, but where the semantics representation is at so high level that can be understood and modi ed by everyone that knows about operational semantics.
