Research Overview: Real-time Monitoring and Control Techniques for Resilient Systems
Current work is focused on the development of small yet accurate structures to measure the impact of oxide breakdown and NBTI effects in CMOS circuits. The goal is to enable distributed sensor networks on large chips for real-time feedback regarding degradation due to various reliability mechanisms. An analysis of the failure distributions for dominant reliability failure mechanisms has been conducted to support the appropriate use of sensors for real-time monitoring and characterize the effectiveness of such methods.
Future work in this area will focus on refinement of monitoring structures and high-level methods to utilize the information obtained with such circuits. Architectural techniques to reduce uneven wearout on large scale multiprocessors is also being investigated with a collaborative team.
Previous research includes SRAM techniques for resilient systems, low-power signaling techniques and some work on variability reduction in post-layout optimization algorithms.
