hi, I am designing pads in 6 metal layer Magna 0.18um. I have successfully designed pads involving M1~M6 (all metal layer), and it passed the calibre DRC.

now I am designing a pad for IO, and I decided to only used M5 & M6, but it cannot pass the calibre DRC. It insists/ guides to use all metal layer to pass the DRC.

my question is: is there a (dummy) layer to make a device under it not checked by the DRC?

Hi,

There will be layers by which you can make tool to avoid checking the DRC, but it is not the correct way you can proceed with.
Please go through the DRC rule Dec on how to create PADs.

And still if you are looking for such layers, u can go through the layer definitions from tech file for its particular technology.
