我也是更新到PCB时出错，找到原因如下：我在原理图里放置差分对时为了符合规则更改了NET的名字（改成_N...
答:在PCB设计中,AD软件提供了批量增加差分对的功能,但是由于软件的某些原因会导致一些差分对没有创建成功,所以当对这些没有创建成功的差分对进行差分走线就会出现如图5-196所示的报错,提示“没有发现差分对”,解决办法为重新给该差分网络单独创建差分对,从而进行差分走线。
如图使用网络标号的连线方式,做差分对布线,并在对应引脚放置差分符号,编译原理图的时候报错"Missing Positive Net for differential pair [DA], negative net [DA_N]…",意思是左边的DA_N和DN_P无法构成差分对(相互之间都缺少对方),右边则报错只含有唯一的的DA_N和DN_P(相同的网络符号构成连线,缺一不可,而且...
设置差分线:设计(D)->类(C)->Differential Pair Classes->All Differential Pair ->右击,添加类(USB是90Ω,HDMI是100Ω,大部分是100Ω差分阻抗)->点击右下角panels->PCB->点一行选择差分->点击添加->输入引脚标号(正Positive Net 和负Negative Net)和名字(模块名)->会高亮(若不高亮,则选择Mask模式-将Norm...

Positive Net- displays the positive (+) net in the current differential pair. Differential pairs use a naming convention that requires the relevant nets to use a common prefix, followed by a consistent positive/negative suffix, e.g.,TX0_PandTX0_N. Click the down arrow to view a...
Note that as well as an individual net, you can mask a class of nets (if any classes are defined), and also multiple nets (by holding the CTRL key as you click in the PCB panel to select a net name). AP0135 (v1.7) May 21, 2008 1 Interactive and Differential Pair Routing ...
