Using CTL formulae as component abstraction in a design and verification flow

International audienceIn the context of component-based design, the verification of global properties (involving several components) is difficult to achieve, due to combinatorial explosion problem, while the verification of each component is easier to perform. Following the idea of [24], we propose to build an abstraction of a component already verified, starting from a subset of its specification described as CTL formulae. This abstraction replaces the concrete component and alleviates the state-space explosion problem for checking global properties expressed in ACTL
