In addition, a well-defined SVA library is part of the verification methodology where generic sequences are reused. SpletFor any property φ there exists a safety property φs and a liveness property φ L such that φ = (φ S ∩ φ L). The last of these facts is known as the decomposition theorem and can be proved by topological arguments. The safety-part of a property φ is the topological closure of φ, that is, the least safety property containing φ. headsokz cold weather headgear
