I can't find the spice model for n/pfet_06v0 in the gf180mcu PDK which seems to be what the standard cells use in the design I synthesized with openlane. Where is that device model? And out of interest, why are the standard cells using the 6V device?

isn't this <https://github.com/google/globalfoundries-pdk-libs-gf180mcu_fd_pr/blob/main/models/ngspice/sm141064.ngspice#L47034> ?

or <https://github.com/efabless/globalfoundries-pdk-libs-gf180mcu_fd_pr/blob/main/models/ngspice/sm141064.ngspice#L47037> in the efabless's fork

Ah thank you! so do i want to include all of these then?
```pdks/gf180mcu/gf180mcuC/libs.tech/ngspice/design.ngspice
pdks/gf180mcu/gf180mcuC/libs.tech/ngspice/sm141064.ngspice
pdks/gf180mcu/gf180mcuC/libs.tech/ngspice/smbb000149.ngspice```

and what is the last one? I already have the first two

looking at it it seems to add some additional params and equations for the primitive devices

What is Linen?
