Abstract

We address two problems of assessing the influence of power- supply variations on timing analysis. We present a method to assign a supply-dependent hold margin; and we describe a method to accurately characterize logic gates for the sen- sitivity of delay on supply-voltage variations. We use a com- mercial microcontroller as a design example.
