已试验如果改为LVS POWER NAME ?VCC? ?VDD?
结果还是可以通过lvs。
仍然存在warning:non-identical power or ground name(layout extra pins:VDD GND)
不知道这个警告需要重视吗?
谢谢版主指点,我打算去查查看SVRF文档。

对了,版主,在修改了lvs rule中的lvs power name ?VDD? ?VCC?后,得到的报告中的warning:这个warning的红色部分,提到的算法algorithm是什么样的一个算法?
为何在设置了lvs power name后就可以将错误(non-identical power or ground name)变成同样的警告?
