Abstract
A method uses a SAT solver operating to cycle k to find bugs in a model having finite computation paths therein, wherein said bugs are on computation paths of less than length k. Another method includes adding an additional state variable to a model to be checked, where a governing state machine of the additional variable has a 'sink' state. The method includes having a translation using the additional variable whenever a state indicates a bad state and performing satisfiability solving with the model and the translation.
