电源板块进行layout XL的时候报了奇怪的错，该怎么调？

龙斗士

   如题，这边对cadence中的电源模块进行layout XL的时候报了几个warning，这个东西不管的话好像LVS会报错，请问一下，这个该怎么解决？是有关什么的问题？电阻、电容还是MOS管啊？

绝大部分warning都不会影响lvs结果，建议确定一下接线是否正确

即使这个waring是标红的也不影响吗？那它对整体的电路会导致失调或者误差过大吗？

好的，我试试这个

请问楼主解决了吗？我最近也遇到同样的问题了，卡了好久

有详细解释了，麻烦踢我一下，我也碰到过类似的报错，不过是出现在我拿公共库的A版图过验证的时候，结果中有错误点，我通过结果定位错误在版图哪个位置时，工具自动把我本地库之前copy的A版图弹出来并在它上面展示错误点，主视窗就报这个错，我按上面的指导操作了一通也没用，最后把本地库里面的版图删掉才算不出现这样的情况，不太理解哪出问题了

目前大致可以确定是电阻的问题，需要调整一下。但是调到什么程度我也不清楚，只能慢慢试了
