07/07/2022, 1:54 AMHow did you install the skywater pdk?
s
Shridhar Ambady
07/07/2022, 2:02 AMinstalled all the dependencies like magic and xschem and ngspice and all that first
Shridhar Ambady
07/07/2022, 2:03 AMthen I just cloned the repo and did ./configure, make, and sudo make install
Shridhar Ambady
07/07/2022, 2:03 AMmade sure to use the --enable-sky130-pdk on configure
Shridhar Ambady
07/07/2022, 2:04 AMand then copied the xschemrc file from the pdk into my working directory
m
Mitch Bailey
07/07/2022, 3:21 AMThe pdk is installed with the
open_pdkss
Shridhar Ambady
07/07/2022, 3:40 AMyes, that's the repo I installed
Shridhar Ambady
07/07/2022, 3:40 AMthese are the instructions I went through
Shridhar Ambady
07/07/2022, 3:40 AMm
Mitch Bailey
07/07/2022, 4:00 AMSo your pdk is at
~/share/pdkss
Shridhar Ambady
07/07/2022, 4:03 AM/usr/local/share/pdks
Shridhar Ambady
07/07/2022, 4:03 AMI used default install locations for everything

Shridhar Ambady
07/07/2022, 4:38 AMit doesn't exist at all
Shridhar Ambady
07/07/2022, 4:39 AMI got this error when I did "make" on the open_pdk repo, I'm wondering if its related

07/07/2022, 5:12 AMThis error must be resolved before going anywhere further. The 'Error 1/2' message is not of great help. If anything fails, delete the whole open_pdks, reclone again, and try to rebuild again. Ensure you have lot of free diskspace.
s
Shridhar Ambady
07/07/2022, 5:25 AMplenty of disk space, ~60GB left
Shridhar Ambady
07/07/2022, 5:26 AMthere's a "sky130A_make.log" file, looking through that for clues
Shridhar Ambady
07/07/2022, 5:30 AMI keep seeing an error that looks like this:
Shridhar Ambady
07/07/2022, 5:30 AMError message output from magic script:Could not find file 'minimum.tech' in any of these directories:. $CAD_ROOT/magic/sys $CAD_ROOT/magic/sys/currentCannot load technology "minimum" for initializationm
Mitch Bailey
07/07/2022, 5:37 AMCould you post your
sky130A_make.logs
Shridhar Ambady
07/07/2022, 5:37 AMI think I may have found the issue, I tried reinstalling magic and saw there was a fatal error when I tried compiling it,
fatal error: GL/glu.h: No such file or directoryShridhar Ambady
07/07/2022, 5:37 AMthis was fixed by installing libglfw3-dev libgl1-mesa-dev and libglu1-mesa-dev
Shridhar Ambady
07/07/2022, 5:38 AMim now recompiling open_pdk

Stefan Schippers
07/07/2022, 5:48 AMGood!, I also got in similar situations, the golden rule is always check the status of every installation before moving further.

Shridhar Ambady
07/07/2022, 11:17 AMI think I have everything working!
Shridhar Ambady
07/07/2022, 11:17 AMSuccessfully able to create schematics in xschem and simulate in ngspice
