VLSI design has marched into the realm of Deep Sub-Micron (DSM) processes, where the minimum feature size is well below 1 ?m. These advanced processes enable designers to implement faster, bigger and more complex designs. Integrated Circuit (IC) design has seen a revolutionary progress in the past two decades with shrinking sizes of VLSI fabrication processes. This has an advantage of fabricating millions of transistors in a single chip IC. On the other hand it also creates many challenges in Deep Sub-Micron (DSM) technologies.
