摘要: This paper is part of our ongoing effort to replace I/sub DDQ/ testing. We analyze the effect process drifting based on Sematech Project S121 data, and present a simple efficient way deal with these phenomena, when using previously proposed test procedure Delta histograms. also different variance sources in same context. Following this analysis, we propose validate an innovative strategy for optimization use current vectors (patterns) shorter settling time concept partitioning. These new results developments confirm pertinence reduction reveal possibilities terms targeting either better quality or time.
