Abstract
In Chap. 2 we covered technologies and in Chap. 3 we saw how these technologies interface with physical design. Here in Chap. 4 we now provide an end-to-end overview of the physical design process, namely how to physically construct the layout of an electronic circuit. In this chapter we present the fundamental knowledge an engineer must possess to carry out this task. In Chap. 5 we then discuss each of the specific physical design steps in further detail. We begin the chapter by introducing the design flow (Sect. 4.1), design models (Sect. 4.2) and design styles (Sect. 4.3). Next, we investigate various design tasks and related tools (Sect. 4.4), before discussing optimization goals and design constraints (Sect. 4.5). Up to this point our treatise has focused mainly on the digital design flow. In Sect. 4.6 we introduce the characteristics of, and differences between, analog, digital, and mixed-signal design flows. Looking toward the future, we conclude the chapter by presenting two different yet complementary visions for analog-design automation to overcome the analog-digital design gap (Sect. 4.7).

Notes
- 1.
We use the term “VLSI circuit” to denote pure digital ICs, which represent the leading edge in circuit complexity.
