Tcd density drc violations

[sudheer_1706]

Hi,

I'm getting tcd density violations for my db. I've already generated calibre feol and beol fills. I've two pnr dbs, fills are generated in the same fashion for both of them. But one is getting tcd density violations and other is not getting. Pls help me.

Have you inserted tcd cells by hand? That is usually recommended as they are large and the fill utility can struggle to find space in your design for them
