NettetAdvance in technology nodes of integrated circuit (IC) fabrication has introduced increased variation. This presents new challenges for delay testing. To address this challenge, speed-binning based on on-chip delay sensor measurements has been proposed to supplement current speed binning methods. NettetIn practice, inference about integrated variance is drawn from discretely sampled data. Here, we split the sampling period into sub-intervals containing the same number of price recordings and estimate the true range. In this setting, we also prove consistency and asymptotic normality.

NettetThe autoregressive root of integrated variance, IV t, and realized variance, RV t (h), coincide for any h, while their moving‐average roots are different. However, when h goes to zero, the moving‐average root of realized variance denoted by λ(h) converges toward the moving‐average root of the integrated variance process (denoted by λ).
