我怎么也找不到Allegro说的那个unrouted net,请问要如何解决?

请千万回答我这个问题啊,不然我都要对allegro失去信心了!

就是Display -> Status...中显示的"...Unrouted nets: 2/498....."

显示所有的Rats,怎么也找不到啊,不能自动定位,太弱了吧

用 tools ->report 把unconnect pin 的消息打出来,帖上来,让大家看一下。

这些引脚是在原理图库中设置为无连接的引脚。难道就是指这些吗?
Orcad  和 allegro 对于无连接 引脚的详细处理规则是怎样的?一般应该怎么做最好呢——要保证原理图DRC时无错误或警告,PCB检查中无错误?
