> > But gschem can do schematic capture for ASIC even though that’s not its target. The difference is that gschem doesn’t limit what you can draw. It’s quirky and limits *how* you can express what you need, but I’ve never found it incapable of expressing a circuit. It gives you a few crude primitives and a few ways to compose more complex objects from simple objects. A few layers of that, and you have a 6000 component mixed-signal ASIC.

Did you look at element/footprint file format also? Is it possible to have vias in a footprint? Put the drawing primitives in a footprint at copper or solder mask layer?

In such case the only large thing missing is possibility to reference externally defined pins/pads from within a footprint.
