램프 입력에 대한 RC-class 연결선의 지연시간 예측을 위한 해석적 연구

초록

This paper presents a simple and fast delay metric RC-class interconnects under saturated ramp inputs. The RC delay metric under saturated ramp inputs, called FDM(Fast Delay Metric), can estimate delay times at an arbitrary node using a simple closed-form expression and is extended from delay metric under step input easily. As compared with similar techniques proposed in previous researches, it is shown that the FDM technique involves much lower computational complexity for a similar accuracy. As the number of circuit nodes increases, there will be a significant difference in estimation times of RC delay between the previous techniques based on two circuit moments and the FDM which do not depend on circuit moments.
