Abstract
Until now, definition of optimization problem is overly depending on the designer. But, the product systems such as System LSI become very complex system. Then, the designer can't define the optimization problem correctly. For this problem, we propose the system design method (SDSI-Cubic). This method is constructed from system definition to optimization through the dividing the optimization problem hierarchically. In this paper, this system design method applies to the system design for System LSI.
