 Abstract
 The major work of the graduation project is mainly depends upon EDA in tool''s Multisim 8 softwares to realize to the commonly used high-frequency circuit''s simulation, 8 carries on the description and the analysis take Multisim as the basic tool to the commonly used high-frequency circuit''s basic characteristic, proves these high-frequency circuit''s reasonable characteristic.
 First, the paper simply introduce that the development of the EDA technology,。Next，the paper introduce the Multisim 8 tool softwares, mainly include: The Multisim 8 simulation analysis method, provides simulation instrument as well as software''s elementary operation eo. Finally use this software has carried on the simulation to the commonly used high-frequency circuit, has LC and the crystal oscillator, the small signal tuned amplifier, the varactor frequency modulation and the phase discriminator, other nonlinear circuit separately. And to the simulation result analysis, these commonly used high-frequency circuit''s characteristic obtained the proof.
 The study indicate that Multisim8 has provided the formidable circuit analysis function, particularly has provided the quite comprehensive simulation analysis method, may carry on compared to the laboratory more analysis tests
 The characteristic of this article lies in showing to carry on the simulation analysis and the test using the Multisim 8 softwares to the commonly used high-frequency circuit, is not only convenient, is economical, moreover time-saving, highly effective, has the very high use value.
