Modeling the Effect of Redundancy on Yield and Performance of VLSI Systems

The incorporation of different forms of redundancy has been recently proposed for various VLSI and WSI designs. These include regular architectures, built by interconnecting a large number of a few types of system elements on a single chip or wafer. The motivation for introducing fault-tolerance (redundancy) into these architectures is two-fold: yield enhancement and performance (like computational availability) improvement.
