Dynamic analysis of SA/RT models using Spin and modular verification

This paper presents the integrated use of the Spin Model Checker in conjunction with Structured Methods (SA/RT). The graphical model is translated into a Promela program in which we prove assertions about the desired behaviour of the system. We also provide support for modular verification, by separately verifying different components of the model and deducing the desired global properties from the previous verifications. The above approach is then illustrated using a steam boiler system as a case study.
