An Electronic Design Assistance Tool for Case Based Representation of Designs
In precedent based design, solutions to problems are developed by drawing from an understanding of landmark designs. Many of the key design operations in this mode are similar to the functionalities present in case based reasoning systems: case matching, case adapting, and case representation. It is clear that a rich case base, encoding all major product types in a design domain would be the centerpiece of such an approach. EDAT (Electronic Design Assistance Tool) is intended to assist in preced
