Abstract (englisch):
Software verification is a tedious process that involves the analysis of multiple failed verification
attempts, and adjustments of the program or specification. This is especially the case for complex
requirements, e.g., regarding security or fairness, when one needs to compare multiple related runs
of the same software. Verification tools often provide counterexamples consisting of program inputs
when a proof attempt fails, however it is often not clear why the reported counterexample leads to
a violation of the checked property. In this paper, we enhance this aspect of the software
verification process by providing \emph{DIbugger}, a tool for analyzing counterexamples of relational
properties, allowing the user to debug multiple related programs simultaneously.
