    LVS Subtype error at layout

    Hello,

    When I run lvs I get error : mismatched instance subtypes and description is : layout instance of X1407/M2 MP(pch_alvt_mac)| Schematic Instance: MM1==17(pch_lvt_mac).
    Is this some kind of connection error?
    I have already checked vias and it seems that everything is connected correctly. Should I double check it?

    It would be very helpful if someone could explain me possible reasons that this error occurred.

    Thanks in advance :)

    looks lt is a device mismatch. Try changing your pmos pcell from pch_alvt_mac to a pch_lvt_mac device

    Check for marker layers or idenification layers, place both versions of the pcell and look for sub layer differences, ie poly and below
