In previous work, we have introduced a contract-based {\em realizability checking} algorithm for assume-guarantee contracts involving infinite theories, such as linear integer/real arithmetic and uninterpreted functions over infinite domains. This algorithm can determine whether or not it is possible to construct a realization (i.e. an implementation) of an assume-guarantee contract. The algorithm is similar to k-induction model checking, but involves the use of quantifiers to determine implementability.

Virtual integration techniques focus on building architectural models of systems that can be analyzed early in the design cycle to try to lower cost, reduce risk, and improve quality of complex embedded systems. Given appropriate architectural descriptions, assume/guarantee contracts, and compositional reasoning rules, these techniques can be used to prove important safety properties about the architecture prior to system construction.
