👉 Backup math is an essential component of formal verification and model checking, used to ensure the correctness of a system's behavior under all possible scenarios. It involves creating an additional, redundant mathematical model that covers potential counterexamples or edge cases not addressed by the primary model. This backup model is designed to prove that if a property fails in the primary model, there exists at least one scenario where the system behaves incorrectly, thereby providing a clear path to identify and fix errors. By incorporating backup math, engineers can achieve higher confidence in the system's reliability and robustness, especially in safety-critical applications where failure is not an option. This technique complements the primary model by offering a safety net that can catch overlooked issues, ensuring a more comprehensive verification process.
