Yasm: A Software Model-Checker for Verification and Refutation. This paper presents Yasm: a (yet another) software model-checker based on the Counter-Example Guided Abstraction Refinement (CEGAR) [6] framework. A number of well-engineered software model-checkers are available, e.g., Slam [1] and Blast [12]. Why build another one? Traditional software model-checkers build over-approximating abstractions of the programs they analyze and typically bias their analysis towards proving that a (safety) property of interest holds (verification). On the other hand, since model-checkers are widely known for their bug-finding abilities, they are often used for refutation. In this case, the above approach seems unreasonable: why introduce spurious behaviour and make it more difficult to find a real bug? For such circumstances, one would just want to prove that the property is false (refutation). No witness for that is required.
