Using Aspects with Object-Oriented Frameworks

We investigate potential uses of aspect-oriented programming in the context of object-oriented C++ frameworks used in the development of VLSI CAD applications. We use existing applications to explore the use of different kinds of aspects. We differentiate between framework-based aspects and application-specific aspects. Framework-based aspects modularize cross-cutting code based on how an application uses or extends an object-oriented framework. We propose the use of a library of framework-based aspects that can be developed for and leveraged across a family of frameworkbased applications. Application-specific aspects allow modularizing existing cross-cutting code in VLSI CAD applications. Preliminary results for each type of aspect are presented, along with challenges in identifying and using aspects.
