The Computer Systems Design Environment (CSDE) project is an attempt at automated design of computer systems. The project develops a system which will accept functional statements of requirements from the designer (utilizing a user-friendly dialogue); translate those requirements into software and hardware primitives; evaluate those primitives and develop a proposed system using a Library of Realization Volumes. The CSDE will also verify that timing requirements have been met by the proposed hardware and software; and present the system design to the designer (in a user-friendly format). The CSDE will be a prototype based on an existing feasibility demonstration version which has verified the concept. The prototype version will explore issues of adaptability, user friendliness and design system performance. This paper is a plan for the development of the CSDE. (Author)
