Hi, Everyone. Attached is my Calibre LVS report. There is no error shown in my LVS report, but some warnings show up in LVS extraction report. Could these warnings affect the final results? Thanks!

No, I wouldn't think so.

The warnings just inform that the power PATHCHK couldn't be performed because of unattached power labels and ports. So the electrical - not the physical! - connectivity between MINUS/GROUND and PLUS/POWER respectively - and of Vbias - had not been checked.

You should perhaps highlight the concerned nets in the extracted layout and make sure that they are connected correctly.
