Abstract

We consider the problem of checking whether a distributed system described in SDL is consistent with a set of MSCs that constrain the interaction between the processes. In general, the MSC constraints may be both positive and negative. The system should execute all the positive scenarios "sensibly". On the other hand, the negative MSCs rule out some interactions as illegal. We would then like to verify that all the remaining legal interactions satisfy a desired global property, specified in linear-time temporal logic. We outline an approach to solve this problem using Spin, building in a modular way on existing tools.
