“has no driver”的解决方法
今天在进行原理图绘制完成后,对其进行编译,发现出现好多相同的错误:“......has no driver”,找了很久,没有发现什么错误。经过慢慢摸索:原来,我开始只是新建了一个schematic文件,即单单是对一个sch文件进行编译,所以,出现了前述的“has no driver”的error!
解决方法:
将schematic原理图添加到某工程,再编译就不会出现那些error了。
还可参考:
解法一:你使用的元件对应的引脚是输入的,可以改变原理图中对应元器件的引脚属性解决。
解法二:在protel中,软件会检查你的输入管脚有没有连,这样的好处是提醒画图的人还有输入管脚悬空的,我们知道,在电路系统中,大部分输入管脚是不允许悬空的.所以建议画图的人在做原理图库的时候尽量把元件管脚的属性加上,这样可以不让自己出错.如果有输入哪个管脚必须悬空的话,可以在上面添加忽略ERC检查.这样编译的时候就没有警告了!
解发三:在做元件封装的时候,管脚的electrical type有很多选择,一般情况下,选择passive就没事了
解发四:设置属性。在Project-Error Reporting-Violations Associated with Nets
Signals with no driver中,选择no report,
