The rate of evolution varies among sites within proteins owing to structural and functional constraints. The main pattern of variation is due to structural constraints: evolutionary rates increase ...

EDA (Electronic Design Automation) cell characterization tools have been used extensively to generate models for timing, power and noise at a rapidly growing number of process corners. Today, model ...

To allow engineers to control design margins, improve design robustness and increase parametric yield – all part of variation-aware design – EDA giant Synopsys Inc. has added extensions to the Liberty ...
