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.

Usually, the foundry (like TSMC) is offering to their customers the special dummy metal fill runset for Calibre (or for Hercules or for another tool). Check it, maybe you already have such runset.

Thank you, Oratie.

I checked the CMP analyzer manual, but it says only TSMC is supported, which means Calibre cannot be used for our ST 28nm. Even if ST is supported, we need to provide a variety of materials, like, thickness, etc. I think we may not be able to provide those stuff unless the faudry is willing to help us do this.

Thanks.

Hi,

I don't know whether you have checked it or not this link: https://www.youtube.com/watch?v=pZNOx3M9nb8.

Hope it helps you.

By the way, what is the reason of doing metal filling in Calibre and not in SoC Encounter? I'm just curious.

Thanks.

For deep nano technologies, it is obligatory to use foundry provided runset for doing final (sign-off) dummy metal,poly,active filling. Yes, you can use capability of SoC Encounter or ICC for doing that, still at the end, you should use official runset for full-chip filling. Because, the rules for dummy insertion and distribution are too complicated, it is impossible to respect all of them in any PnR tool.

Hello,
I'm a beginner and I need to run auto fill TSMC. But I don't know how to do that. I use Cadence and run Calibre on Cadence.
Is it possible to added auto fill to Cadence.
Thank you

You will have to contact TSMC if your supervisors have not already. They have a template and also foundry runsets which they are obligated to provide to their customers. Writing a runset on you own could be a major challenge.
You can also search for it in the mentor graphics support website
