It seems that `ANTENNAGATEPLUSDIFF` is missing from Metal1 in all of the techlefs: https://github.com/fossi-foundation/globalfoundries-pdk-libs-gf180mcu_fd_sc_mcu9t5v0/blob/e0e80f5a6522f10b82165d3aeab9b8ee28e89849/tech/gf180mcu_4LM_1TM_11K_9t_tech.lef#L71
That seems to be wrong, do you agree?

I think so.

I guess it won't really have any impact since nothing is routed on met1, it's the standard cell themselves.


[2026-06-15 2:38 p.m.] mole99
Right, That's probably the reason!

Then I'll leave it as is and only adjust the other layers.
