Feature-Based High Level Design Tools

This paper describes the computer science orientated course on VLSI design at Royal Holloway and Bedford New College, the primary aims of which are to enable students with very limited electronics knowledge to design and fabricate full custom VLSI devices, and to introduce them to the use of high level design tools.

Abstract Feature modeling enables the specification of a model with standardized high-level shape aspects that have a functional meaning for design or manufacturing. In this paper an interactive graphical approach to feature-based modeling is presented. The user can represent features as new CSG primitives, specified as a Boolean combination of halfspaces. Constraints between halfspaces specify the geometric characteristics of a feature and control feature validity. Once a new feature is defined and stored in a library, it can be used in other objects and positioned, oriented and dimensioned by direct manipulation with a graphics cursor. Constraints between features prevent feature interference and specify spatial relations between features.
