A data flow model for prototyping reactive systems. (PhD Transfer Report)
A prototype is defined to be the first of its kind, or a model for another of its kind. In general manufacturing, building a prototype is an accepted way of validating a design before manufacturing resources are committed for mass production. In electronic engineering prototyping is also an accepted method of design validation, often described as "breadboarding", where components are connected together to produce a working model of the system.
