Analyzing Formal Requirements Specifications Using an Off-the-shelf Model Checker

We study the use of an off-the-shelf formal verification tool, namely the explicit-state model checker SPIN, for various analyses related to SCR (Software Cost Reduction) formal requirements specifications. Unlike other studies, where model checking is used for a specific purpose in the context of SCR analysis (e.g., test generation or invariant verification), we use the model checker as the only analysis tool, for consistency checking, completeness analysis, property verification, etc. Moreover, to assess our characterization of the various analyses in terms of model checking, we develop a case study (a pacemaker specification), more complex than those typically found in the SCR literature.
