Whether metal filler over macros or not in Encounter

[hkrist]

Hi all,

If I add the metal filler in the region of core whether the metal filler are added on the top of macros(e.g. sram or other analog circuits).

I have asked my friend, he said the metal filler would be added all over the region. But it was added all the region except the top of macros, I want to confirm the problem.

P.S. There will be DRC errors in metal density when I use calibre to verify it

Hi Hkrist,
You can add it all over the region,
I think your memories meeting required metal density already(Generally memories/IP will be closed with DRC/LVS so internally they will take care of density as well)
And i think they ll have blockages as well.
So you dont need to worry about that, just carry on with your Calibre DRC checks.

The metal-fills wont be add over the macros if the macro has routing blockage.
