Formal verification

A tool that checks a system against a specification

In formal verification a checker is a model checker: an algorithm that exhaustively searches the states of a finite-state system to decide whether it satisfies a specification written in a temporal logic, returning a counterexample trace when it does not. Clarke, Emerson, and Sistla's 1986 Automatic verification of finite-state concurrent systems using temporal logic specifications established the approach for concurrent programs. The referent is a verification procedure and its yes/no-with-counterexample output, and it has nothing to do with a backgammon piece beyond the common word 'checker'.[1]

Unit
A decision that a system model satisfies a temporal-logic specification
Recovery means
Not applicable
Measured by
Evaluated by whether the specification holds across all reachable states, with a counterexample if it fails
