Computer Simulation Analysis and Application of Electric Circuit Based on Multisim9

This paper mainly introduce the characteristics of applying Multisim9 software in circuit simulation comparing with traditional circuit design method ,and the methods of circuit simulation using Multisim9.Then with examples of electronic circuit ,such as negtive feedback amplification electronics circuit and A/D、D/A circuit.It illustrates the specific methods of simulation and analysis in analog circuit and digital circuit based on virtul electronics workbench.Through compareing the result with the theoretical analysis,it can conclude that the technology of electronics design and simulation is convenient and highly efficient. Classical design and analysis methods of the electronic circuits based on circuit experimentation will be completely replaced by electronic circuits design and simulation based on computer simulation technology. Electronics Design Automation ( EDA) has become the reality.
