The problem of analyzing concurrent systems has been investigated by many researchers, and several solutions have been proposed. Among the proposed techniques, reachability analysis—systematic enumeration of reachable states in a finite-state model—is attractive because it is conceptually simple and relatively straightforward to automate and can be used in conjunction with model-checking procedures to check for application-specific as well as general properties. The system validation problem considered here is the problem of verifying that the original specification is itself logically consistent. If, for instance, the specification has a design error, an implementation is expected to pass a conformance test if it contains the same error. A validation for the logical consistency of the system, however, must reveal the design error. An automated analysis of all reachable states in a distributed system can be used to trace obscure logical errors that would be very hard to find manually. This type of validation is traditionally performed by the symbolic execution of a finite state machine model of the system studied. The author presents an overview of the existing validation techniques and methods. Specified and analyzed systems are presented as reachable state graph. The implementation of the aggregate specifications validation system is also presented.
