Hello, I’ve been trying to install open_pdks It configures with no errors at all but when i run [make] , it runs for about 10 minutes then crashes and the whole system shuts down at this line, can anyone please help?

What's the last thing that was output in the log files for the build?

Have you checked HDD space? I found my installation went from 10GB before this step to over 94GB (peak) before dropping back to 81GB.

"make timing" on the standard cell libraries produces a lot of large .lib files, but 94GB seems excessive (understatement). A lot of the space can be reclaimed after the open_pdks install by deleting the original sky130 libraries (if you cloned them yourself) or by doing "make distclean" (if you let open_pdks clone them). You can also reclaim space after the open_pdks install by doing "make clean" and "make veryclean". None of that helps with the memory overhead during the build, however. I think if you have low disk space overhead, the best option is to get a precompiled version of the PDK, such as from volare.

Perhaps I'm overdoing it with what I'm installing. My command line was:

./configure --prefix=/opt --enable-sky130-pdk --enable-sram-sky130 --enable-osu-t12-sky130 --enable-osu-t15-sky130 --enable-osu-t18-sky130

should be sufficient (equivalent to what you did, except (1) the prefix you used is, I think, going to put everything in the redundant path

/opt/pdks/share/pdks

, and (2) never use

--with-ef-style

(used on the efabless online platform only). But I would not expect those minor differences to cause anything to crash, or hang, or take up inordinate amounts of memory or disk space.

Thanks Tim, those suggestions sound good. I'll run through another install proceeds later in the week and monitor the effect on disk usage as it goes.
