I donot have much Experience in Place and route operation. The problem is that I have completed the place and routing of the core area as well as the IO pads. When I run DRC verify geometry I have no violations in the core area but in the Corner IO pads I get two short erros ( LeftBottom and Top right corner pads) in the dummy cell pins. It looks strange because even other two corners have the same dummy Pins but there are no short errors. The two Violations I am getting are
SHORT: Pin of Cell io_pad_left_bottom_corner & Blockage of Cell fillperi_S_0 ( M3 )
Bounds : ( 112.000, 1.900 ) ( 112.000, 2.100 )
SHORT: Pin of Cell io_pad_right_top_corner & Blockage of Cell fillperi_N_78 ( M3 )
Bounds : ( 1568.200, 1503.300 ) ( 1568.200, 1503.500 )
Can anyone please advise me on how to fix it.?
