Object-oriented design methodology applied to the modeling of USB device and bus interface layers

Important changes are taking place in the EDA world as System-on-Chip (SoC) IC products create new market segments. These ICs have multiple complex cores that need to be integrated in order to allow the chip to perform the complete system function. At the moment chip-processing equipment is capable of producing technology that is far more advanced than what the design tools can do. This design gap can be reduced by the use of new tools and methodologies based on high levels of electronic systems abstraction. Object-oriented techniques and languages have been proven to significantly increase engineering efficiency in hardware development. Many benefits are expected from their introduction into electronic modeling. Among them are better support for model reusability and flexibility, more efficient system modeling, and more possibilities in design space exploration and prototyping. In this paper we present an object-oriented methodology used to create the models of USB device and bus interface protocol layers.
