@Jazim Ibrahim Looks like there’s a device size discrepancy.
R3
and
R9
in the schematic don’t match the layout length.

Okay. But I changed the value of length if these resistor to match the resistance value in both schematic and layout.

LVS doesn’t look at the resistance - just the length and width.
