Abstract

Design patterns have demonstrated major practical uses for cost savings and modular design in software engineering. For safety-critical systems, however, such patterns should also provide formal guarantees that critical safety properties are met. We leverage the power of rewriting logic and parameterization available in Real-Time Maude to add a formal basis for analysis of a novel safety pattern for medical devices. We demonstrate practicality and applicability of our pattern by instantiating it to a pacemaker specification, and we validate our pattern by verifying the safety invariant in the pacemaker instantiation.
