Zusammenfassung: | Reactive synthesis is the task of automatically deriving a correct
implementation from a specification. It is a promising technique for the
development of verified programs and hardware. Despite recent advances in terms
of algorithms and tools, however, reactive synthesis is still not practical
when the specified systems reach a certain bound in size and complexity. In
this paper, we present a sound and complete modular synthesis algorithm that
automatically decomposes the specification into smaller subspecifications. For
them, independent synthesis tasks are performed, significantly reducing the
complexity of the individual tasks. Our decomposition algorithm guarantees that
the subspecifications are independent in the sense that completely separate
synthesis tasks can be performed for them. Moreover, the composition of the
resulting implementations is guaranteed to satisfy the original specification.
Our algorithm is a preprocessing technique that can be applied to a wide range
of synthesis tools. We evaluate our approach with state-of-the-art synthesis
tools on established benchmarks: The runtime decreases significantly when
synthesizing implementations modularly. |
