Abstract
The principal structures used in an object-oriented CAD design environment (OOCADE) intended for use in connection with VHDL design are described. OOCADE establishes a hierarchical knowledge representation system for design entities (objects) using multiple inheritance (and inferential distance to resolve ambiguities) across a variety of user-definable relations. The design environment, VIOLET, which is the central part of the OOCADE, supports data abstraction, attribute inheritance, and dynamic binding. The discussion covers the basic concepts, the features of VIOLET, dynamic binding, the iconic user interface, and constraints and integrity checking.Keywords
