DOMINO noise model: a new crosstalk noise model for dynamic logic circuits

DOMINO gates are more vulnerable to crosstalk-induced functional failures compared to static CMOS gates. Previously developed noise models generate a pessimistic noise analysis because the effect of the keeper in DOMINO is not properly incorporated. In this paper, a new crosstalk noise model is proposed for DOMINO logic gates. Our noise model takes the effect of the keeper into account and provides a more accurate noise measure. We define the degree of conservatism for noise models and show that our noise model dramatically reduces the pessimism.
