<@U017E7L119N> I have a PR on github that allows `make -j N`  to work properly. With `-j 16` it takes about 4 minutes here.

If you care to test it : <https://github.com/google/skywater-pdk/pull/125>

I'm sure positive build report in the PR would be welcome :stuck_out_tongue:

can test, me need some help on the commands though, how can I pull this changes?

```git remote add smunaut <https://github.com/smunaut/skywater-pdk.git>
git remote update
git merge smunaut/liberty-makefile-rework```

I’m getting gazillions of these:
```
Makefile:79: libraries/sky130_fd_sc_ms/v0.0.2/timing/sky130_fd_sc_ms__tt_025C_1v80_ccsnoise.d: No such file or directory
Makefile:79: libraries/sky130_fd_sc_ms/v0.0.2/timing/sky130_fd_sc_ms__tt_100C_1v80.d: No such file or directory
Makefile:82: warning: overriding commands for target `clean'
scripts/make/conda.mk:85: warning: ignoring old commands for target `clean'```
I’m getting 100% utilization now, which seems good!

Ok, I think the 'clean' command is throwing these, I used `rm` instead of `rm- f` to avoid the warning if it doesn't exist.

Also conda env has its own `make clean` which conflicts ... I'll need to clean that up.

ok, other than that, works great so far! thank you!
