PINCETTE - Validating Changes and Upgrades in Networked Software

Networked control systems ensure today's dependability of essential infrastructure such as water, electricity and transportation. Over a life cycle of tens of years, maintenance upgrades of the software running these control systems must not introduce new software errors or otherwise break existing functionality. The EU FP7 project PINCETTE addresses this challenge by employing a combination of static and dynamic software verification tools. The changes between versions are used both as guidance for improving efficiency of software verification, and also to define new notions of correctness. We report on current progress and initial validation results by our industrial partners.
