The implementation or design is regarded as a model of the system, whereas the specifications are properties that the model must satisfy. [2] An important class of model-checking methods has been developed for checking models of hardware and software designs where the specification is given by a temporal logic formula.
CSP: Communicating sequential processes; formal language for describing patterns of interaction in concurrent systems. FDR2 is a refinement checking tool for CSP, comparing two models for compatibility. DVE input language: a system is described as Network of Extended Finite State Machines communicating via shared variables and unbuffered channels.
In addition to model-checking, SPIN can also operate as a simulator, following one possible execution path through the system and presenting the resulting execution trace to the user. Unlike many model-checkers, SPIN does not actually perform model-checking itself, but instead generates C sources for a problem-specific model checker. This ...
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
The second chapter focuses on creating an appropriate model for concurrent systems, where multiple parts of an algorithm (set of instructions) can be carried out simultaneously by different machines or parts of a machine. Chapters 3 explores types of rules that a transition system may satisfy: linear time properties.

The task addressed by BLAST is the need to check whether software satisfies the behavioral requirements of its associated interfaces. BLAST employs counterexample -driven automatic abstraction refinement to construct an abstract model that is then model-checked for safety properties.
