当我用ERC检查时,出现如下告警: Error Report For : DocumentsSheet0.prj 28-Jan-2008 13:40:28 #1 Warning Unconnected Net Label On Net D0 Sheet1.Sch D0 #2 Warning Unconnected Net Label On Net D1 Sheet1.Sch D1 #3 Warning Unconnected Net Label On Net D2 Sheet1.Sch D2 #4 Warning Unconnected Net Label On Net D3 Sheet1.Sch D3 #5 Warning Unconnected Net Label On Net D4 Sheet1.Sch D4
End Report 这是什么引起的,难道我的bus这样用法不对吗? |
