一个比较白痴的问题。。。希望有人帮我

我是Cadence菜鸟，问的问题总是很白痴，所以帖子总是没人回答，希望这次能有人帮帮我~~~~
5 O; {4 |, A7 {: j% g我画了一个原理图，后来在做用PCB editor生成PCB板时发现原理图有错误，然后我重新打开原理图用DRC检查，发现好多错误，有一些我已经纠正了，但是还有一部分错误我确不知道原因，如下：

我发现这个问题的原因了~~~就是这个工程是由多个板子构成的，另一个板子的原理图我没画出来，所以显示有的引脚悬空，我想问一下这样可以生成PCB板吗？我在PCB中导入网表时出现了如下错误：

[DRC0007]的错误一定要注意，一般情况下是因为某个net孤立引起的，这种的要根据坐标仔细检查，很有可能是该net是单端连接，与其他的同一个net没有联接上造成的
[DRC0006]的错误有的可能是net没有联接上造成，也要仔细确认一下

谢谢啦！很有用，记下了！
