no dc path to ground from node
Dear all,
I use calibre -pex. My circuit has some dummy cells and my layout also has these. I run drc and lvs and they are ok. So I run pex. Then I simulate my post-simulation by hspice. But there are some errrors like below. How do I do ?
If I don't kill my dummy cell, how do I do? If you know, please tell me . Thanks.
