Introduction 3 performed at various stages in the lifecycle of a VLSI device, including during the VLSI development process, the electronic system manufacturing process, and, in some cases, system-level operation. In this section, we examine these various types of testing, beginning with the VLSI development process. 1.2.1 VLSI Development Process The VLSI development process is illustrated in Figure 1.2, where it can be seen that some form of testing is involved at each stage of the process. Based on a customer or project need, a VLSI device requirement is determined and formulated as a design specification. Designers are then responsible for synthesizing a circuit that satisfies the design specification and for verifying the design. Design verification is a pre-dictive analysis that ensures that the synthesized design will perform the required functions when manufactured. When a design error is found, modifications to the design are necessary and design verification must be repeated. As a result, design
