@User: We originally had a set of SPICE files from SkyWater that were provided without reference to a specific version number. For a while we stuck them in V1.3.0. Eventually we decided that it is not difficult to write a script to do the conversion ourselves, which I finished last week (except for handling Monte Carlo simulation). We should have that in the repo fairly soon, after we write some script to break those files up and separate out the subcircuit definitions from the models and move the subcircuits into the base library model directories under the cell name to which they belong. Once that is done, there will be SPICE models in all of the library versions in sky130_fd_pr_base/rf/rf2.
