Chapter 13. Synthesis of clock and power/ground networks

About This Chapter

Clock distribution networks and power delivery systems are the two largest types of on-chip interconnect networks. They both play a crucial role in the correct operation of a circuit. A clock network delivers a synchronizing signal across the chip to coordinate the flow of data. A power/ground (P/G) supply network provides a reference voltage for determining the status of a transistor (on or off) and also the current for switching a transistor.

This chapter addresses many issues that affect the integrity of clock networks or P/G networks. We begin with a discussion of the timing, power, and robustness issues that one must consider when designing a clock network or P/G ...
