关于LVS中遇到missing injected Instances的问题

时间：10-02 整理：3721RD 点击：
遇到的奇怪的事情,画好的版图分别assura和calibre跑LVS,assura可以通过,并且后仿成功,但是用calibre的LVS就过不了,主要的提示就是missing injected Instances,搜了好久找不到产生这个的原因.版图的连线和器件都能确保正确,毕竟assura后仿结果也比较符合..请问有谁遇到过这种情况..?该如何解决?谢谢.....LVS的结果如下

检查电源和地 版图中是否标对

有可能要宣告 GLOBAL

电源和地我重新确认了一下..能和原理图对应起来..

能否讲得更详细一点?之前画版图没有考虑这个问题...也能通过LVS...这次比较奇怪...

NMOS 少 PMOS多 查一下 N_WELL　是不是　
圍到　NMOS 那邊了
// LVS REPORT OPTION
改成　LVS REPORT OPTION　A B C D S V
報告會詳細些

我仔细看了一下,这个错误有可能是Calibre把我其中的一个器件识别成inv或者别的了,然后没法匹配上,这个我要怎么处理呢?

CDL中把电源和地 声明为全局信号

LVS如下

复制代码

把GDS和CDL rul发给我，我给你试试



谢谢~请问我要如何发给你呢?

看來還有 AVDD 和 VDD 電源的問題
如果P MOS ( S ) 接 AVDD 那 (B) 接 VDD
你的網表 可能要修改

谢谢你的答复,我修改了一下还是不行...最后把版图重画了一遍就过LVS了....具体是什么原因导致的我还是不清楚....

在LVS的option中选择看看吧。

AVDD是电源吗?你没定义为电源啊。另外跑一下FLATEN的试试

grobal的问题。定义一下power和ground

重画了一遍就过LVS了，那就说明版图还是有问题。

应该是net错误，换个方式（flatten）跑也许会报出net error

同样遇到问题，求解！

我也觉得是版图问题，只是错误的报出方式不同而已，我以前就遇到过，是我不小心把两个不同连接的diff连错了，结果找的我想死的心都有了当然也有可能是你的cdl错了



请问一下标对是什么意思?我的电源地有问题，高了好长时间都没有搞好啊

怎么定义全局变量啊?

帖子中，显示电路部分全局信号没有被识别，需要再CLD中，*.GLOBAL后标准电源信号就可以了，
需要注意，添加的电源信号必须跟电路中的全局信号一致，例：vdd！ ,如果标注vdd！：P在calibre中是不识别的。
*.GLOBAL vdd！:P vdd！

可以在，LVS OPTION 设置下，在supply选项中 ，分别把power ，gnd 的信号名字都写上去。
