An Information Model for an Engineering Information System Gio Wiederhold CIS conference room, Stanford University, 11am Thursday 4 Dec. 1986 We will prsent concepts about the information flow during the process of the design of engineered objects, specifically electronic circuits and systems. The intent of the model was to locate effective interfaces between information-processing tasks and to consider the type of information which is transmitted through those interfaces. This work was sponsored by the Air Force VHSIC program to provide a basis for the development of standards for interfaces in engineering information systems. Bid proposals for building a prototype of a system to sopport the design process are now being prpared. The concepts relate only indirectly to the architectural choices for engineering information systems. A perfect match of the conceptual nodes identified in the information-processing model to engineering system components cannot be expected. System modules may encompass tasks that an information model views as distinct, and may sometimes carry out only part of an information task. We are using some of the concepts in a proposal to develop techniques to support parallel design with formal tools. We will discuss these issues at the end of the presentation. -------
