Abstract

A comprehensive simulation flow is demonstrated to assess the negative-bias temperature instability (NBTI) impact on the performance and power of digital logic circuits based on the 14-nm node FinFET technology. Fully calibrated technology computer-aided design simulations are used to determine the preaged and postaged device characteristics; the results are used for calibrating the BSIM-CMG compact model. Standard cell libraries are characterized next, by only threshold voltage shift ( Δ V_T) and by both Δ V_T and subthreshold slope shift ( Δ SS). Various benchmark circuits are synthesized and analyzed, and their timing degradation is compared to ring oscillator results. The consequence of ignoring Δ SS on OFF current and static power ( P_static ) is estimated.
