这几天画了一个版图，结果跑LVS总是出现如下图的错误
图中的ERC错误是因为所画的有些器件的B极不是连接到GLOBAL电位的，而是连到一个器件的输出端。
验证分析的结果是calibre会把版图上的OUT1_B这条net认成OUT0_B,还有就是认不出INB这条net。
然后从上图中可以看到有20个错误，但如果我把版图左右翻转、上下翻转或者90度翻转，错误的个数会改变，变成23、26、27或者28个错误。
如果我按照下图在LVS OPTION中设定好它的电位，结果就是下下张图中显示的——错误没有了。。。
求各位大神指教这是怎么回事，还有就是这张版图能直接这样投入使用不，还是说需要改正？（试着改了几天了，就是解决不了这问题啊 ，求有懂这问题，或者遇到过并解决掉这种问题的达人帮忙啊，谢谢！）
以下附上LVS report（是跑LVS出现20个错误时的report）
