Then I get a ton of spice errors:

@Matt Venn I only directly used the skywater-pdk trees in the early days, after doing some manual patches. Now i only use the pdk as installed by

open_pdks

, because lot of fixes (like order of parameters and many more) that are necessary for ngspice are now done by @Tim Edwards

open_pdks

great work.

is this not a part of the volare installed pdk? I'd have to install this separately?

I use sky130 pdk by installing it with open_pdks. If you are using another toolchain or container things may be different.

I just follow the instructions to install openlane

Good i am not the only one having difficulties in finding old posts on slack. I can't find anything in most cases and i have to re-answer identical things again...

I find the slack search to be pretty poor

@Matt Venn: Always use

sky130.lib.spice

with the

.lib

card, not a lower-level file with the

.include

card. If you can find the PDK installation with

libs.tech

, then (according to what you posted before), you want to do:

.lib /home/matt/work/asic-workshop/shuttle7/pdk/sky130A/libs.tech/ngspice/sky130.lib.spice tt

Make sure you've copied the

spinit

file from the same directory above into your local directory and rename it

.spiceinit

or else it will take 30 minutes to start the simulation.

thanks Tim, that works
