各位好，
新人向各位请教一个问题， 在使用SYSTEM SI 的提取POWER SI中PCB的S参数时，出现错误如下：
****Signal Net Statistics for Net DDR_DQS3M*****
Total number of traces buried under pads : 2
.
.
.
****Summary : Signal Net Statistics for the Design*****
Total number of small shapes : 0
Total number of large shapes : 0
Total number of traces buried under traces : 0
Total number of traces buried under pads : 90
Total number of traces overlapping along length : 0
Total number of traces aligned along length : 3
Total number of traces with no reference : 0
请问 traces buried under pads和traces aligned along length 是什么意思啊?怎样才能消除错误?感激不尽！
