. The task addressed by BLAST is the need to check whether software satisfies the behavioral requirements of its associated interfaces. BLAST employs counterexample

Counterexample

In logic, and especially in its applications to mathematics and philosophy, a counterexample is an exception to a proposed general rule. For example, consider the proposition "all students are lazy"....

-driven automatic abstraction refinement to construct an abstract model that is then model-checked for safety properties. The abstraction is constructed on the fly

On the fly

-Colloquial usage:In colloquial use, on the fly means something created when needed. The phrase is used to mean:# something that was not planned ahead# changes that are made during the execution of same activity: ex tempore, impromptu.-Automotive usage:...
