在powerpcb5.0里面，怎样检查pcb的nets和原理图的nets相同与否？

这个应该是可以检查的啊，难道没人会吗？

一通百通

tools/compare netlis（原理图asc,选original design）和（Use Current PCB Design)new designoutput 选options/generate differences report.比较.

我按照你说的方法，点击RUN后，就会显示ECOGEN failed,

为什么会这样啊？

有可是你的ASC格式不正确，你可以把刚从原理图导好的的PCB再导成ASC文件作为原始档保存，以后完成Layout时再compare，若没有问题会出现如下的Layout.log：

哦，的确如此，谢谢谢谢！
