Auto metal fill using calibre

cupidsd

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.

  • Hi cupidsd

    You will need to write a metal fill deck to first read in the design, locate the empty spacing using "density" cmd, do some layer processing and then use "drc check map" cmd to output the fill shapes. As this is a Cadence forum, it would be better if you can get some help from Mentor Graphics forum. : )


    Best regards
    Quek
