Abstract
A description is given of an approach to rapid prototyping that uses a specification language (the Prototype-System Description Language, PSDL) integrated with a set of software tools. including an execution support system, a rewrite system, a syntax-directed editor with graphics capabilities, a software base, a design database, and a design-management system. The prototyping language lets the designer use dataflow diagrams with nonprocedural control constraints as part of the specification of a hierarchically structured prototype. The resulting description is free from programming-level details, in contrast to prototypes constructed with a programming language. The discussion covers the language and method, rewrite subsystem, design manager, software base, and execution support.
