Specifying a prototyping language in the Cornell synthesizer and the Xinotech program composer

The production of prototypes for large real-time constrained software systems under the prototyping cycle paradigm requires the integration of sophisticated tools. The user interface under development for the computer aided prototyping system (CAPS) requires the interface with a syntax-directed production environment. This environment aids the designer to enter and modify software prototypes specified in the prototype system development language (PSDL.) The Cornell synthesizer generator and the Xinotech program composer are being explored as possible alternatives. The author reports the experiences, accomplishments, and future work
