Expression of Concern: Managing on-chip inductive effects

With process technology and functional integration advancing steadily, chips are continuing to grow in area while critical dimensions are shrinking. This has led to the emergence of on-chip inductance to be a factor whose effect on performance and on signal integrity has to be managed by chip designers and has to be sometimes traded off against other performance parameters. In this paper, we cover several techniques to reduce on-chip inductance which in turn improve timing predictability and reduce signal delay and crosstalk noise. We present experimental results obtained from simulations of a typical high performance bus structure and a clock tree structure to examine the effectiveness of some of the different inductance reduction techniques.
