Constrained synthesis from component libraries

Synthesis from component libraries is the problem of building a network of components from a given library, such that the network realizes a given specification. This problem is undecidable in general. It becomes decidable if we impose a bound on the number of chosen components. However, the bounded problem remains computationally hard and brute-force approaches do not scale. In this paper we study scalable methods for solving the problem of bounded synthesis from libraries, proposing a solution based on the CounterExample-Guided Inductive Synthesis paradigm. Although our synthesis algorithm does not assume a specific formalism a priori, we present a parallel implementation which instantiates components defined as Linear Temporal Logic-based Assume/Guarantee Contracts. We show the potential of our approach and evaluate our implementation by applying it to an industrial case study.
