Low Level Dependent Design Methodology for High Level VLSI Design

In the area of VLSI design automation,since semi-conductor technology has progressed to deep sub-micron,the factors （such as delay,power consume）, that can not be considered in the design phases of high level design,will affect the performance of the design result greatly,and it might cause the performance of physical design result being far from the design aim.For this problem,a low-level dependent design methodology for high-level VLSI design is proposed.In this approach,the parameters and information in lower level which affect the performance are led to the higher level design process so as to make the physical implementation of the higher level design surely satisfy the request of performance.
