Abstract
The highly informative society is progressing. In connection with this, the circuit scale and functions of system LSIs are increasing. Therefore, development of the system design methods for designing a large-scale and complicated system LSI efficiently are needed. To this subject, writers have developed the SDSI-Cubic method as the efficient system design method. Using this method, we have derived the proper 3D system LSI for next-generation cellular phones by constructing a parametric physical model. However, this physical model is insufficient of consideration of a business investment because system LSI cost is evaluated by chip cost and investments for equipment is not evaluated. This means that business evaluation is not made. Therefore, in this paper, by constructing the economic model which evaluates total profit and loss dissolution time as the index of business, we derived proper composition of the 3D system LSI for next-generation cellular phones considering investments for system LSI equipment.
