Abstract
This chapter discusses the analog and mixed–signal simulation. In this chapter, a brief description is provided about the analog simulation and digital simulation. Analog simulators are not obliged to operate at the transistorlevel, they may support multiple levels of modeling abstraction, including digital logic primitives with analog interface characteristics. Digital simulators are based on the concepts of a fixed time-step and an “event wheel” in which events are scheduled to take place at some time in the future. This chapter also discusses digital simulators with native analog capability (a/D), analog simulator with native digital capability (A/d), and full cosimulation of analog and digital simulators (A/D). The chapter describes alternative cosimulation strategies. The majority of cosimulation techniques may be classed as either Unified, Simulation Backplane, Glued, or Coupled.
