| Abstract: | We present a methodology for transforming a functional specification written in Lucid, to an equivalent specification that captures its real-time properties. The enhanced specification consists of a set of equations. These equations can be solved for several properties, including execution time and external requirements, or they may simply be checked for the existence of a solution. Lucid has a set of meaning-preserving transformations, and a proof system corresponding to a behavioral semantics has been constructed. Both of these tools can be used to reason about properties of the specification. The specification is executable and can be used as a prototype for the system being specified. Among other benefits, this allows very precise location of places where real-time constraints cannot be met. We illustrate with an example. It is possible to express architectural constraints within the same formal framework. Thus this type of specification can be used to guide the development of new real-time systems.
