Chip Layout Structural Design Flow with C++ Class Interfaces

From iccad call for paper, the abstract should contain: 1state out clearly and precisely what is new 2point out to signi cant results for 1: what we do is use the ICSP/C++ interfaces to specify structural information and guide the functionnal decomposition on the structure. for 2: it enables layout predictibility early in the design stage and eases functional decomposition for 2 also: it points out that new tools are needed to do this In this paper, we present a system engineering methodology built upon the de nition and implementation of object relationship. We show how class interfaces can be used for structural layout representation throughout all design abstraction levels. With our design process, the engineer uses an extended UML (Uni ed Modeling Language) notation, Scenic and ICS class interfaces and our design CAD programs suite. This paper describe the use of ICSP C++ class interfaces to specify structural information and to guide our tool throughout the functionnal decomposition on the spe cied structure. In this paper, we describe our methodology and the implementation of a prototype.
