Graphical support for reducing information overload in rapid prototyping

The authors discuss the capability of graphical representations to ease the prototyping process and reduce the problem of information overload. The application of information-hiding and multiple views, coupled with ensuring consistency and automatic programming, can improve user productivity. The development of a graphical editor for performing hierarchical decomposition of composite PSDL (prototype system description language) operators for CAPS (computer aided prototyping system) is also discussed. Research on the graphical editor, as it relates to PSDL, indicates that a prototype design can be developed with much greater ease using the graphical editor than with only the syntax-directed editor. The graphical editor will also enhance prototype modification, presentation, and documentation
