Statistical Characterization and STA Primer

Cell model creation for statistical timing analysis is a great primer on Statistical Static Timing Analysis (SSTA). It's written from the viewpoint of the challenges facing statistical library characterization. After reading this article, I wonder how we're *ever* going to have a complete set of SSTA-characterized libraries. Fortunately, the EDA startup Altos, which is where one of the authors works, has a solution under development. Unaddressed by this article is how such characterization will be represented for all the vendors' STA tools. As of now, there is no .lib "Liberty" standard for statistical modeling. We've got a long ways to go!
