“…For example, Table I (see Section II) shows common BEOL corners in which the wire width (∆W ), wire thickness (∆T ) and dielectric thickness (∆H) variations are biased to the minimum or maximum values. 1 Although BEOL parameters have strong spatial correlations within a die [12], different BEOL parameters are not fully correlated [5] [6] [10] [13] [22]. When the parameters are not fully correlated, the likelihood of a worstcase (or best-case) condition on all layers is vanishingly small (if not a physical impossibility).…”

“…To reduce the pessimism in CBCs, various statistical RC extraction and timing analysis methods have been proposed [1] [2] [3]. The main drawback of statistics-based methods is the lack of availability of commercial EDA tools to characterize a RC variation model (e.g., sensitivities of RC to BEOL physical parameters).…”

“…geometric parameters are useful for diverse variability modeling techniques. They are necessary for establishing the parameterized system description in various variation-aware techniques, such as the moment-based timing analysis [7], the Hermite polynomial based statistic analysis [8] and the parametric Model Order Reduction (pMOR) technique proposed in [9]. The sensitivities have been incorporated in the Standard Parasitic Exchange Format (SPEF) [10].…”

“…These sensitivities are necessary for establishing basic formulations in various variation-aware algorithms, such as moment-based timing analysis [1], Hermite polynomial based statistic analysis [2] and parametric Model Order Reduction (pMOR) proposed in [3]. Also, techniques including fast corner generation, multi corner extraction and the variation-aware Static Timing Analysis (STA) presented in [4] are all based on sensitivity models.…”
