CPAchecker is a framework and tool for formal software verification, and program analysis, of C programs. Some of its ideas and concepts, for example lazy abstraction, were inherited from the software model checker BLAST. CPAchecker is based on the idea of configurable program analysis  which is a concept that allows expression of both model checking and program analysis with one formalism. When executed, CPAchecker performs a reachability analysis, i.e., it checks whether a certain state, which violates a given specification, can potentially be reached. 
CPAchecker operates on a control-flow automata (CFA); before a given C program can be analysed by the CPA algorithm, it gets transformed into a CFA. A CFA is a directed graph whose edges represent either assumptions or assignments and its nodes represent program locations.
