auto metal fill using calibre

[haibin]

Hi folks,

I am working on a 28nm project, which requires auto metal fill for our
chip. After googling, I know that Calibre is able to do auto metal
fill. But I have not found any commands or scirpts concerning how to
do this. Can you give me a hint or any comments about using Calibre.
Plus, Calibre SmartFill can do this as well, but we have no such
product.

Thanks a lot.
