急问,calibre怎么提取不了电容
录入:edatop.com 阅读:
弄了好几天,都无法解决,我是第一次做,没有经验,不知道是不是calibre的选项那里没有设置好?还是是stream out 时,选项没有选好,GDSII没有弄对?GDSII是自己是按默认来stream out的。所有的版图是用pcell单元画的。
谢谢!

以前也遇到过这样的问题,可能是lvs的文件中层的定义出错了,需要核对一下。
今天写信,问了一下技术支持,他说电容的mark层错了,应该标在长度上,我标在了宽度上了。可是我用pcell单元直接生成的电容,怎么会出现这种问题呢?
难道是电容的上下两个基板引出的方向不同,电容的长宽的方向会不同?还是系统默认一个方向是宽,如果是这样的话,那这个方向是那个方向呢?
谢谢回答!
还是直接去看看你的command file中关于电容的定义好了,对照一下layout
"他说电容的mark层错了,应该标在长度上,我标在了宽度上了"
这句话如何理解?你是用的什么电容pip还是扩散电容,一般把电容的mark层覆盖在电容上就ok了,当然最好是看一下command file,电容如何定义的。
这些电容单元都是用pcell来生成的,我认为Mark不应该会标错,要不然的画,谁还会用cadence公司的pdk.
所以,我我认为还是应该和电容放的位置,或者是电容的引出端有关系。才弄的这个PIP电容的长宽颠倒了。
但是我突然想起来,在pcell中可以看到电容单元的长宽的,难道只是和电容的引出端有关系?
谁能来补充一下?
对照 mark 层的设置
Mark 没有长和宽之说吧!
我提取的电容感觉不准啊。
Thanks for sharing.
赚点分不容易啊
bd 哈哈
Good jobs!好樣的
