Liveness Verification
ConceptLiveness verification is a formal-verification activity that checks whether a system can avoid states in which it never makes forward progress. In the provided evidence, it is presented as a necessary complement to safety verification for pipelined microprocessors, because a deadlocked processor—or even a device that does nothing—can satisfy some correspondence-style safety checks unless forward progress is also proven.

Definition
Liveness verification is the verification of whether a system can avoid getting into a state where it never makes forward progress. In the cited microprocessor-verification context, liveness is needed to show that a pipelined processor does not stall indefinitely. [1]
