Why
Core voltage library with digital cells, resistors, capacitors and standard transistors.
The library is not for synthesis, but for the stray logic we sometimes need to have in analog schematics.
If you find yourself using lots of digital cells from this library, then consider learning verilog and openlane. It will be smaller.
