ABSTRACT
This chapter provides an introduction to the various simulation types and demonstrates their use through a number of worked examples. Simulation can also be used to perform analyses that are not always possible or desirable on a physical design such as worst-case component tolerances sensitivity analyses and simulating faulty circuits. Simulation packages are usually classified into four types: analog, digital, mixed analog-digital, and block-diagram simulators. The simulation program with integrated circuit emphasis is a powerful computer package used to analyze electrical and electronic circuits. Fourier analysis is a useful tool for examining the frequency spectrum of signals, and PSpice is capable of performing such an analysis using the statement. Electronic circuit designs often involve the use of similar or even identical blocks of circuitry. To describe the repetitive circuitry efficiently, PSpice provides the user with the subcircuit approach. Digital simulators allow the user to check the function and perform a timing analysis of a digital system.
