Dummy MOSFETs for Common Centroid Diff Pair

[melkord]

In a interdigitized or common centroid configured differential pair, e.g., ABBA , do we add dummy for each A and each B ?

if that is the case, do you have the dummies also in schematic to pass LVS?

I add dummies as well in schematic like shown in the picture below.
but if I need to add dummies for each A and each B, it means 1 MOSFET which sliced into 4 parts could have 8 dummies.
Do I understand it correctly or I am missing something here?

When doing common centroid in that fashion you want to add dummies on both ends making it like:
DABBAD.

What sort of connection you make with the dummy depends on your use case.
