比如我画的层次图如下：<br />（1）<br /><img src="https://bbs.21ic.com/upfiles/img/20081/2008128141235782.jpg"><br />（2）<br /><img src="https://bbs.21ic.com/upfiles/img/20081/2008128141416281.jpg"><br />（3）<br /><img src="https://bbs.21ic.com/upfiles/img/20081/200812814157147.jpg"><br />当我用ERC检查时，出现如下告警：<br />Error Report For : DocumentsSheet0.prj 28-Jan-2008 13:40:28<br /> #1 Warning Unconnected Net Label On Net D0<br /> Sheet1.Sch D0<br /> #2 Warning Unconnected Net Label On Net D1<br /> Sheet1.Sch D1<br /> #3 Warning Unconnected Net Label On Net D2<br /> Sheet1.Sch D2<br /> #4 Warning Unconnected Net Label On Net D3<br /> Sheet1.Sch D3<br /> #5 Warning Unconnected Net Label On Net D4<br /> Sheet1.Sch D4<br /><br />End Report<br /> <br />这是什么引起的，难道我的bus这样用法不对吗？ |
