The integrated life cycle model of configurable information system

Proposed life cycle model that allows to integrate all phases of building configurable information system (CoIS) and reduce development time, complexity and cost. The main idea of the model is to integrate the phases of life cycle by a formal description of each stage, the development of formal methods of transition from the results of one phase to another and create an integrated information environment, containing a description of the system at all levels and stages of detail system. We consider the principles of integration and their implementation at all stages of the life cycle of the example of the functional aspect of building integrated circuits.
