Abstract

This paper presents a new model to estimate wire length distribution (WLD) of system on chip (SoC). The WLD represents a correlation between wire length and the number of interconnect, and we can predict power consumption, maximum clock frequency, chip size, etc with the WLD. The proposed model provides a WLD considering each core utilization of several macro blocks in a system LSI. We present an optimization method to determine each core utilization.
