怎么删除差分对属性？
录入：edatop.com 点击：
我在allegro的约束管理器中设置了差分对属性，后面发现这对线要从接插件J1移到J2,在原理图上修改后导入allegro出错，
提示如下：
1 ERROR(SPMHNI-219): Could not add a property to the Allegro database.
ERROR(SPMHNI-361): Diffpair 'HFSDC' is a electrically derived diffpair, cannot be changed.
#2 ERROR(SPMHNI-219): Could not add a property to the Allegro database.
ERROR(SPMHNI-361): Diffpair 'HFSDC' is a electrically derived diffpair, cannot be changed.
#3 ERROR(SPMHNI-219): Could not add a property to the Allegro database.
ERROR(SPMHNI-361): Diffpair 'HFSDC' is a electrically derived diffpair, cannot be changed.
#4 ERROR(SPMHNI-219): Could not add a property to the Allegro database.
ERROR(SPMHNI-361): Diffpair 'HFSDC' is a electrically derived diffpair, cannot be changed.
请问我如何才能删除这对线的差分对属性?
在约束管理器中删除功能不能用啊

PCB里 设置差分线的地方 可以删除差分对
Logic------Assign Differential Pair里选择删除。
谢谢楼上回复，Logic------Assign Differential Pai里也删除不了啊
看来问题出在这里，怎么解决呢?
重新做一闪SI Design Setup就好了，原因不明
谢谢大家的帮助
现在在用刚看到，因为是user defined的diff pair所以不能删除，我碰到的问题主要是在这个上面是有xnet属性，后来我把对应的电阻的ESPICE模型去除了之后，就能删掉这个diff pair了
学习了 谢谢
