【摘要】 电路设计中存在大量重复的电路功能模块,为实现此类模块的设计复用,该文提出一种基于构件的电路设计方法,将电路功能模块封装成构件,用构件设计电路原理图。在已有电路设计软件的基础上实现支持该方法的电路设计平台,从电路原理图到PCB文件的转换过程中,采用就近集中原则进行元件预布局。实验证明,该平台有效降低原理图复杂度,提高电路设计正确性,缩短电路板开发周期。更多还原

【Abstract】 There are many iterative circuit function modules in circuit design.In order to reuse these modules,we proposed an approach which encapsulates circuit function modules into components,and applies these components in the circuit design.Thereby,we accomplished the secondary development on Protel99SE.All the elementary components of the circuit design will be pre-layout through the transforming from SCH to PCB file.The circuit development experiments demonstrate that this kind of circuit platform shorten the circuit development time,reduce the complexity of the circuit design,and improve its effectiveness and the reliability.更多还原
