ah, it seems I’ll need to modify a couple of lines to be able to use run_designs.py on macOS

Hi, I’m struggling to get the skywater-pdk “make” running on my Mac. There is no conda package for “netlistsvg”. How did you work around this (My work around was ordering a Linux workstation, but I guess there is a cheaper solution)

just install that separately and comment it from the yml file

Thanks, that did the trick. Next: Yosys conda module seems to be unhappy with the python version 3.8.3, but i guess I can work around this. Is it OK if I ask you some further questions regarding the flow on macOS?

no prob mate. I’m running with Python 3.7.4 and yosys below:

yosys --version
Yosys 0.9+2406 (git sha1 000fd081, clang 11.0.3 -fPIC -Os)

Thanks. I already have another question: did you use the dockerized version of openLane? I would prefer to have the tools built/installed natively (I have had some bad experiences with docker)

xD that seems to be the general feeling. I installed openroad nativelly and works fine, there are some scripts that need to get modified, but is just a matter of replacing some of the run_* procs inside scripts/tcl_commands/* to use the *_or version instead

OK.. so get a full Openroad install and then adapt the scripts in the openlane repo is a feasible road to take? Is this documented somewhere and are you using macports or brew?

😄 totally doable, the scripts edit are minimal
