由Protel制板EWB仿真电路的实现

The Realization of Using EWB Circuit Simulation to Make Circuit Board with Protel

在一般电子设计与制作中可先用EWB设计电路原理图,再用该软件提供的虚拟仪器和分析工具进行仿真,最后将仿真优化的电路转换成网格表供Protel制板。介绍了由EWB电路仿真到Protel电路制板的工作流程和用Protel制板EWB电路的接口技术。以一个典型的稳压电路为例,阐明其实现的方法与技巧。

During the normal course of electronic design and manufacture, we can first use EWB to design schematic diagrams,then we use fititious instruments and analytical tools provided by the software to carry out schematic emulation. Finally we transform the emulated and improved electric circuit into the net form to make circuit board with ProteL This paper introduces the workflow from EWB circuit simulation to making circuit board with Protel and interface technology to make EWB circuit with Protel. Take a typical voltage stabilizing circuit for example to clarify the methods and techniques of their realization.
