Mitigating Soft Errors in System-on-chip Design

With the continuous downscaling of CMOS technologies, the reliability has become a major bottleneck in the evolution of the next generation scaling. Technology trends such as transistor down-sizing, use of new materials and high performance computer architecture continue to increase the sensitivity of systems to soft errors. Today the technologies are moving into the period of nanotechnologies and system-on-chip (SoC) designs are widely used in most of the applications, the issues of soft errors and reliability in complex SoC designs are set to become and increasingly challenging. This paper gives a review to the soft error in SoC designs and then presents the fault tolerant solution.
