Abstract

Abstraction is a key issue in automatic verification, and it is often performed by a projection on a subsystem that is relevant for the property to check. This paper defines projections for the scenario language of High-level Message Sequence Charts (HMSC). We first show that the projection of an HMSC is not representable as an HMSC, in general. However, we show how that projections of HMSCs can be represented by a larger class of scenario languages, namely by (realizable) compositional HMSCs (cHMSCs). Moreover, we propose an algorithm that checks whether the projection of an HMSC can be represented by an HMSC, constructing the HMSC representation, when possible. This can be used in model-checking the projection of an HMSC specification.
