DELAY ESTIMATION METHOD AND DEVICE FOR CIRCUIT MODEL AND SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To estimate delay of a semiconductor integrated circuit including cell delay.SOLUTION: A circuit model for a simulation of a cell includes a current source model of the cell in which a resistance element is added. A first lamp voltage source is connected to an input side of the cell, and a second lamp voltage source is connected to an output side of the cell.SELECTED DRAWING: Figure 8
