Are you running
make pdk
command right?

Depends on the number of cores, apparently, it is multi-threaded. On my last update, I realized it is now building
sky130A
and
sky130B
which then also doubles the time. Agree, that a speedup would be highly welcome. Maybe @User has an idea.

@User: If you let open_pdks pull and build skywater-pdk, then most of the time is taken up by "make timing" in the skywater-pdk repo, which last I checked was not multithreaded, but that could just be because the file
/sky130/custom/scripts/pdk_download.sh
in open_pdks should have the last line as
make -j$(nproc) timing
instead of just
make timing
.

@User would be cool if you could change this in the makefile.
