| Research Abstract |
We have investigated on a design method that improves manufacturability and tolerance to variation as well as a method for compensating variation and defects. Simplification and regularity enhancement of layout patterns the effect of simplified and regularity-enhanced layouts have been quantitatively examined by simulation and real chip measurements. Vulnerability of FF timing characteristics under within-die variation has been pointed out and variation-tolerant design of FFs is proposed. On-chip monitor circuits for the estimation of die-to-die variation has been also developed.
