#238 Models for npn transistors not available New issue created by Unkraut3 The models for the npn transistors are not listed in all.spice. I tried to manually add the models by adding the following lines to all.spice:

.include "../../libs.ref/sky130_fd_pr/spice/sky130_fd_pr__npn_05v5_W1p00L1p00.model.spice"
.include "../../libs.ref/sky130_fd_pr/spice/sky130_fd_pr__npn_05v5_W1p00L2p00.model.spice"

Depending on npn model I try to use use I now get the following error from ngspice: • 1x1µm² device:

Undefined number [dkisnpn1x1]

• 1x2µm² device:

Undefined number [dkisnpn1x2]

The parameters are present in the source files, e.g.

sources/sky130-pdk/libraries/sky130_fd_pr/latest/cells/npn_05v5/sky130_fd_pr__npn_05v5__t.corner.spice

but apparently are not transferred during conversion. Adding to the following to my spice file before including all.spice enables to perform simulations using typical values:

.param
+ dkisnpn1x1=8.7913e-01 dkbfnpn1x1=9.8501e-01
+ dkisnpn1x2=9.0950e-01 dkbfnpn1x2=9.6759e-01
+ dkisnpnpolyhv=1.0 dkbfnpnpolyhv=1.0

It would be great if the npn transistor models would be available for ngspice. RTimothyEdwards/open_pdks
