Abstract
 PSpice software has a powerful rendering capability of the circuit diagram, circuit simulation features, graphics and post-processing components production function symbols to graphically input, automatic checking circuit to generate charts, circuit simulation and calculation. It uses a very wide range, not only can be used for circuit analysis and optimization of design, can also be used for electronic circuits, signal circuits and systems courses and computer-aided teaching.
 The article has done a brief introduction on PSpice software, and has pointed out its characteristics, interfaces and basic method of calculation. The article introduces a method to analyze circuit by using PSpice, this method has characters of simple city and high efficiency. Then some model building，programming and simulation of several typical examples about the article are given in explaining the powerful calculating functions in Electric Circuit Analysis。and thus has points out the prospect of PSpice at that field．
