ABSTRACT

In this chapter, we discuss the mixed-signal coupling problem and review various techniques to model, analyze, and validate it. In Section 26.2, the random noise inherent to electronic devices and the deterministic noise generated by circuits are dierentiated. en, we discuss the physical phenomena responsible for the creation of undesired signals in a digital circuit and the mechanisms of their transport to other parts of the system, mainly via the substrate. Various modeling approaches and simulation techniques of digital noise generation as well as substrate impedance network determining noise coupling are reviewed in Section 26.3. Section 26.4 describes an application of the analysis techniques to placement and power distribution synthesis.
