摘   要
     Electronics Work bench(簡稱EWB)，中文又稱電子工程師仿真工作室。EWB5.12軟件的仿真功能十分強大，近似100%地仿真出真實電路的結果。而且，它就像在實驗室桌面或工作現場那樣提供了示波器、信號發生器、掃頻儀、邏輯分析儀、數字信號發生器、邏輯轉換器，萬用表等廣播電視設備設計、檢測與維護必備的儀器、儀表工具。采用EWB虛擬電子工作臺，即通過計算機軟件仿真的方法，對電子線路分析進行模擬，下面以電子線路中設計的一個穩壓電源實際電路為例，詳細講述其操作程序，以掌握電路仿真分析的應用方法。EWB軟件最明顯的特點是：仿真手段切合實際，選用元器件、儀器與實際情形非常相近。用EWB進行仿真模擬實驗，實驗過程非常接近實際操作的效果。各元器件選擇范圍廣，參數修改方便，不會像實際操作那樣多次地把元件焊下而損壞器件和印刷電路板。軟件不但提供了各種豐富的分立元件和集成電路等元器件, 還提供了各種豐富的調試測量工具：各種電壓表、電流表、示波器、指示器分析儀等。是一個全開放性的仿真實驗和課件制作平臺,給我們提供了一個實驗器具完備的綜合性電子技術實驗室。

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.
