Chapter 45 Summary: The PCB Design Process This chapter examines the traditional design process, which the author terms “TTL engineering,” and compares this style with the “right the first time” virtual prototyping method that employs simulation tools to model and analyze the design. Readers will learn how to gradually switch from hardware prototyping to simulation, why some engineers claim that simulation does not work, and the role of such tools in a good system-level design approach.
