@User after some time i was trying to rebuild the whole open_pdks infra. After cloning the open_pdks, doing all the git clone of the skywater-pdk, doing the 'make timing', building magic (all successfull) , i did (in ~/open_pdks) a:

./configure --with-sky130-source=~/skywater-pdk/libraries --with-sky130-local-path=~/pdks

that went well, however after a '`cd sky130'` under open_pdks, and a '`make`' i got an error:

bash: line 1: /home/schippes/open_pdks/sky130/sky130A/libs.tech/ngspice/sky130_fd_pr__model__r+c.model.spice: No such file or directory

and the reason is that there is no ngspice/ directory under

open_pdks/sky130/sky130A/libs.tech

. Am i doing something wrong?
