Hi all,

I am using a 90 nm SiGe process from GlobalFoundries. I noticed that the PDK provides 'Viabar'. This is basically a continuous wall, made of via layer, and not discrete vias.

However, I have never seen them being used before. So, my question is, are there any considerations that I should keep in mind while using viabars? Or would it be okay, as long as I pass DRC?

Thanks.
