Statistical static timing analysis (SSTA) has emerged as a viable technique to capture increasing process variations in 90nm technologies and beyond. To obtain realistic results from a statistical timer, careful attention to the statistical gate delays and correlations between them is required. However when using SSTA early in the design phase, no correlation information is available. This paper addresses this problem and proposes a novel path-based algorithm, which covers arbitrary correlations by computing bounds for the true path delay distribution. Our bounding method is based on the theory of copulas as well as an efficient bounding improvement technique. The efficiency and accuracy of the proposed algorithm is demonstrated on ISCAS'85 benchmark circuits. Over all testcases and all spatial correlation structures the average error of the 95 th quantile points is smaller than 7% and the run-time is drastically reduced compared to a transistor level SPICE Monte Carlo simulation.
