After running LVS, the following error reported:

LVS completed. INCORRECT. See report file: lvs. report

1.What type of property error is this, and how to remove this error?

For information, using 0.35 AMS PDK(H35), schematic is of diode formed by using PNP VERT10 bipolar transistor.


please help
