摘   要
     Electronics Work bench(简称EWB)，中文又称电子工程师仿真工作室。EWB5.12软件的仿真功能十分强大，近似100%地仿真出真实电路的结果。而且，它就像在实验室桌面或工作现场那样提供了示波器、信号发生器、扫频仪、逻辑分析仪、数字信号发生器、逻辑转换器，万用表等广播电视设备设计、检测与维护必备的仪器、仪表工具。采用EWB虚拟电子工作台，即通过计算机软件仿真的方法，对电子线路分析进行模拟，下面以电子线路中设计的一个稳压电源实际电路为例，详细讲述其操作程序，以掌握电路仿真分析的应用方法。EWB软件最明显的特点是：仿真手段切合实际，选用元器件、仪器与实际情形非常相近。用EWB进行仿真模拟实验，实验过程非常接近实际操作的效果。各元器件选择范围广，参数修改方便，不会像实际操作那样多次地把元件焊下而损坏器件和印刷电路板。软件不但提供了各种丰富的分立元件和集成电路等元器件, 还提供了各种丰富的调试测量工具：各种电压表、电流表、示波器、指示器分析仪等。是一个全开放性的仿真实验和课件制作平台,给我们提供了一个实验器具完备的综合性电子技术实验室。

Abstract

Electronics Work bench (i.e. EWB), Chinese calls electronic engineer the simulation work room. The EWB5.12 software's simulation function is very formidable, the approximate 100% place simulation has the real electric circuit's result. Moreover, it looked like in the laboratory tabletop or the job site has such provided the oscilloscope, the signal generating device, the sweep tester, the logical analyzer, the digital signal generator, the logical switch, broadcast television equipment designs, the examination and the maintenance necessary instrument, the measuring appliance tool and so on avonmeter. Uses the EWB hypothesized electronic workstation, namely through the computer software simulation's method, carries on the simulation to the electronic circuit analysis, below a voltage-stabilized source actual electric circuit which designs by the electronic circuit in is the example, narrated in detail its operation sequence, grasps the circuit simulation analysis the application method. The EWB software most obvious characteristic is: The simulation method is realistic, selects the primary device, the instrument and the actual situation is close. Carries on the simulation modelling with EWB, the experiment process is close the actual operation the effect. Various primary devices choice scope is broad, the parameter revision is convenient, will not look like actual operation such to weld many times the part damages the component and the printed wiring board. Not only the software has provided each kind of rich primary devices and so on discrete component and integrated circuit, but also has provided each kind of rich debugging measuring tool: Each kind of voltmeter, ampere meter, oscilloscope, display analyzer and so on. Is an entire open simulation experiment and the courseware manufactures the platform, has provided an apparatus complete comprehensive electronic technology laboratory to us.
