A INTEGRATED IC-CAD SOFTWARE DEVELOPMENT ENVIRONMENT

This paper presents a three-dimensional mathematical model of IC-CAD software development environment, in which a series of tools for the IC-CAD software development are integrated. According to the model, a IC-CAD Software Development Environment (ICSDE) is under development. ICSDE describes and manages the information flows of IC -CAD system design procedures. It improves the software reliability, maintainability and reusability as for the implementation of the engineering management models. Upon this approach, it is possible for the development of IC-CAD software to follow the rules of software life cycle, and proceed with the automatic data-flow management, so as to make the uniformity of user ideas, design style, design concept, tools etc... and the software hereditability is obtained.
