Summary

Chapter 11 investigates the looming challenges of silicon process variations to robust circuit design. As the increasing variations significantly degrade design quality, it is critical to consider manufacturability and yield factors at the design stage. Design strategies to mitigate their impacts are examined, ranging from specific designs of clock distribution and memory units, to more general approaches of robust analog and digital designs for nano-CMOS technology. Besides design techniques for manufacturability, statistical analysis of circuit performance is also presented, in order to effectively handle process variations and improve system yield.
