any familiarity with this error? happens only at SS for the mentioned native device

@Ahmed Reda I have this one on

test_nmos.sch

schematic and it works in the ss corner. I am using the

combined

new models:

.lib .../share/pdk/sky130A/libs.tech/combined/sky130.lib.spice ss

Try to change transistor W and L

@Stefan Schippers It doesn't work if you disable the

ng_nomodcheck

option. I occasionally disable this option as a more cautious approach.

@Ahmed Reda Good catch, nice to know. Thank you for the update!
