Abstract

Iterative simulation-based design is a laborious process that depends on a designer’s intuition, prior experience, and knowledge about the entity being designed. Synthesis-based design, on the other hand, is systematic. If optimization is used, it can yield a good design in less time than in trial-and-error design. In this chapter, optimal synthesis procedures that are developed for microsystems and their components are described. Four categories of synthesis problems are identified for different levels of abstraction of microsystems. The first level, where the architecture of the system and its subsystems are identified, is highly subjective and is often left to the designer's discretion. The second level, where a system-level model is constructed with reduced-order models for the subsystems, is well suited for parametric optimization. The methods for this are simple but effective. The third level, where the geometry of the components is to be determined, is the most time-consuming step and is also the most suited step for systematic synthesis. The methods for this are described for six different types of problems – many involving multiple coupled energy domains. The fourth level, where the microfabrication process and lithography mask layouts are to be generated, is a practically important synthesis problem. But it has not received as much attention as it deserves. A few methods that are developed for this are presented. The chapter also notes some open issues and challenges concerning the synthesis of microsystems.
