photo RIS

RIS addresses the fundamental challenges induced by aggressive nanometric scaling, including: high defect densities caused by increasing process, voltage and temperature variations, accelerated aging, EMI and soft errors; as well as stringent power constraints imposed by fast increasing power densities and temperatures, and battery-life requirements in mobile applications.
To address these challenges, the RIS group works at multiple levels of system architecture for developing robust design approaches (and tools for their qualification), including: circuit, bloc, microarchitecture, array-level, and software. Our goals are multiple, and concern the development and use of self-healing and self-adapting approaches for: mitigating fabrication faults (in particular those induced by process variations), to improve fabrication yield; mitigating field failures (in particular those induced by aging) to increase product lifetime, as well as those induced by voltage and temperature variations, EMI and soft errors to improve reliability; operating the circuits at aggressively low voltage levels to aggressively reduce power.
