Abstract

AbstractWe work in the context of a tool set developed for the Italian Railway Network supporting the migration of legacy relay-based interlocking systems to a new software-based implementation. We propose to generate test cases from the analog implementation in a way that they are significant for a comparison with a cycle-based computational model, by leveraging stable states abstraction. Our methodology found actual bugs in the new code that were missed by other analyses, and aids in documenting the expected differences with the legacy behaviors.
