As of last week, my schematic editor Mosaic now has a desktop installer for Windows, Mac, Linux (and can be installed in an existing conda environment of course) This will make it much easier to get simulating on your own computer. For working with sky130, for now you need to manually add the models, as I show in the video, but in the future there will be a way to load the pdk in an easier way.
