Not much actually. There is a huge problem with EDA where only established tools can be used. Where Free tools are available, its hard to get PDKs from the foundrys unless you are part of a university or a firm. The free tools lack some important features to make them robust ( like a good parasitic checker) etc. There are several groups trying to bring this awareness, for example FSIC is pretty interesting (https://wiki.f-si.org/index.php/FSiC2019 https://wiki.f-si.org/index.php/FSiC2019)
