Establishing specified properties of a system using formal proofs about a precise model. Formal verification connects an implementation to a formal specification; correctness of the model and its assumptions still matters when applying the result to a physical system.

Formal verification is a rigorous mathematical approach used to prove or disprove the correctness of computer systems, algorithms, and hardware designs with respect to a certain formal specification or properties. Unlike traditional testing methods, which can only provide a degree of confidence based on the tests performed, formal verification aims to provide definitive guarantees about a system's behavior.
