WARN： （SOCLF-58）： cell 'FILL8' has been found in DB so only antenna data will be load.Any other data will be skipped.

WARN： （SOCLF-200）：Pin 'Y' in macro "TBUFX12" has no ANTENNAGATEAREA attribute defined.

encounter lef file

No issue on it. ITS just warning message. You ingore this if you are not worry about antenna violation on metal layer mostly on SI part.

I agree with aravind, WARN （SOCLF-58） is a none issue and WARN （SOCLF-200） is telling you that cell TBUFX12 has no antenna data. At worst you need to create antenna data for that cell.
