@Userthe reason is that in '`all.spice`' (which is in turn called from

sky130.lib.spice

) the only model that gets included for pnp is :

.include "../cells/pnp_05v5/sky130_fd_pr__pnp_05v5_W0p68L0p68.model.spice"

This means that the 3.4x3.4 can not be simulated out of the box (it might be by manually including the model which does exist). Thats not a big problem though. If you need to reference the other bigger one just change the

model

attribute at instance level. May be @User can suggest what is the best default, but again its a minor issue. You can always override default models as explained.
