Successive, formal refinement is a new approach for specification of embedded systems using a general-purpose programming language. Systems are formally modeled as abstractable synchronous reactive systems, and Java is used as the design input language. A policy of use is applied to Java, in the form of language usage restrictions and class-library extensions to ensure consistency with the formal model. A process of incremental, user-guided program transformation is used to refine a Java program until it is consistent with the policy of use. The final product is a system specification possessing the properties of the formal model, including deterministic behavior, bounded memory usage and bounded execution time. This approach allows systems design to begin with the flexibility of a general-purpose language, followed by gradual refinement into a more restricted form necessary for specification.
