공정 기술의 스케일링이 진행됨에 따라 LSI(Large Scale Integrated Circuit)의 타이밍 클로저에 있어서 공정 변동이 주요 관심사로 대두되고 있습니다. 이러한 문제를 극복하기 위해 가장 효율적인 성능 추정 방법 중 하나로 기대되는 SSTA(Statistical Static Timing Analysis)가 집중적으로 연구되어 왔다. 본 논문에서는 출력 전환 시간의 변화를 연구한다. 먼저 입력 천이 시간이 느리고 출력 부하가 작은 경우 기존의 1차 감도 기반 접근 방식으로는 천이 시간 변화를 정확하게 표현할 수 없다는 점을 분명히 합니다. 두 번째로 전압의 작동 마진에 대한 출력 전환 시간의 2차 의존성을 밝힙니다. 우리는 마지막으로 광범위한 입력 천이 시간과 출력 부하 조합에서 출력 천이 시간의 추정이 지속적으로 정확해지는 절차를 제안합니다.

Abstract: Process variation is becoming a primal concern in timing closure of LSI (Large Scale Integrated Circuit) with the progress of process technology scaling. To overcome this problem, SSTA (Statistical Static Timing Analysis) has been intensively studied since it is expected to be one of the most efficient ways for performance estimation. In this paper, we study variation of output transition-time. We firstly clarify that the transition-time variation can not be expressed accurately by a conventional first-order sensitivity-based approach in the case that the input transition-time is slow and the output load is small. We secondly reveal quadratic dependence of the output transition-time to operating margin in voltage. We finally propose a procedure through which the estimation of output transition-time becomes continuously accurate in wide range of input transition-time and output load combinations.
