The development of an integrated system design environment

A four stage system design environment is proposed which includes requirements specification, hardware software separation, module specification and system integration stages from a systems integration perspective. As part of realizing this paradigm, a system level specification language, DODAN, is introduced. Based on this specification language, a prototype, DAA, is implemented which addresses the systems level requirements specification stage. Another prototype, DARMS, was implemented to experiment with the module specification stage. This four stage model is described along with experiences in implementing and working with the requirements specification and module specification prototypes.>
