What is BLAST in program model checking: The abbreviation is Berkeley Lazy Abstraction Software Verification Tool (BLAST) is a software model checker for C programs. The main goal of BLAST (BLAST website) is to be able to check that software satisfies behavioral properties of the interfaces it uses. The Blast employscounterexample-driven automatic abstraction refinement to construct an abstract model that is model checked for safety properties. The abstraction is made on the fly, and only to the needed precision.
