Hi there, the

esd_xfet_g5v0d10v5

symbols don't appear to work with either TT_MODELS or Corner: tt include blocks. Is there an import missing?

In the normal open_pdks installation, calling

.lib sky130.lib.spice tt

should be including the file

corners/tt.spice

which in turn includes

sky130_fd_pr__esd_xfet_g5v0d10v5__tt.corner.spice

from the

sky130_fd_pr

library (where I am assuming that you are using

xfet

to indicate either

nfet

or

pfet

).

That is really strange. I can see that they are there but for some reason xschem and ngspice will not use them.
