Hi all,

What if hot spot found in some area of block? How you tackle this?

Thanks........

It would purely depend upon your scenario, some of which could be :

You can add additional power stripes at the hotspot.
If you found hotspot around macros (usually power hungry macros like PLL, analog macros) , you can make power rings around your macro.
If your standard cell density is huge at the hotspot, try adding some partial blockages at those areas to reduce standard cell density.
If you don't have congestion problem, make your via size bigger.
If its a full chip, place your power pads near hotspots.
