dxp原理图常见错误

主要是画dxp原理图的注意事项

原理图常见错误principle of common mistakes

1、ERC报告管脚没有接入信号ERC report no access to signal pins

1）创建封装时给管脚定义了I/O属性creation package to the pin at the definition of I/O attribute

2）创建元件或放置元件时修改了不一致的grid属性，管脚与线没有连上。create components or modify components placed inconsistent grid attributes， and the lines do not pin connection;

3）创建元件时pin方向反向，必须非pin name端连线。create components reverse direction when the pin， non-name-pin connections.

2、元件跑到图纸界外：没有在元件库图表纸中心创建元件。 components went to the drawings profession ： no paper charts component library center components.

3、创建的工程文件网络表只能部分调入pcb：生成netlist时没有选择为global。the creation of the document network table works only partially transferred PCB ： netlist generation did not choose to global.

4、当使用自己创建的多部分组成的元件时，千万不要使用annotate. When the use of their own creation， multi-component element， we must use annotate.
