Abstract

As the IC technology scales down, the effect of IR drop/ground bounce becomes increasingly significant. IR drop and ground bounce can compromise the gate driving capability and degrade the IC performance, and even can make IC functional failures. Hence, it is crucial to capture this effect efficiently and accurately in order to improve circuit reliability. In this paper, we proposed a timing model with consideration of IR drop and ground bounce. Our model can be derived directly from the existing timing tables (e.g. Synopsys db or CLF tables), which are used in normal timing analysis. Compared with the traditional k-factor approach, our method does not require SPICE netlist and SPICE simulations. Moreover, the accuracy of our model is better than k-factor approach.
