@User: I should probably add "mcon" as an alias so that it matches the skywater documentation. I don't like the SkyWater nomenclature. "Via2", for example, connects m2 to m3. Therefore the contact type that connects li to m1 should be "licon", right? But SkyWater calls licon the contact that connects down from li. Magic traditionally names all the contacts to the first layer of metal, again, according to the material of the bottom type (pc, ndc, pdc, etc.). So I have maintained consistency but I am in direct conflict with the documentation. Adding "mcon" as an alias would help a bit.
