內容摘要：

With the rapid scaling down of feature sizes and increasing of operating frequencies in VLSI, System-on-Chip has become necessary for many applications. Timing, noise, power consumption, and process variations are all the issues that need to be optimized in a complex SoC design. In this tutorial, we will cover some of the most important optimization techniques for modern SoC designs.

After a brief review of critical design issues in SoCs, we will focus on a set of optimization problems and present efficient algorithms for solving them. The first problem addresses the global interconnects with delay of multiple clock periods. We propose a technique called wire retiming to place registers on these wires while maintaining the functional correctness of the whole circuit. The second problem considers how to optimally buffer a whole circuit such that its timing constraint is satisfied. Statistical optimization techniques for process variations may also be presented if time permits.
