tscircuit maintainer here, we actually do support constraint-based modeling for footprints, although we don't use it often because we also support "short string" footprints which are often faster

What I'm missing is something like <pinheader>, just for generic connectors - say, <connector variant="[microusb,miniusb,usba-female,usba-male,vga-male,vga-female]">.

Also, for resistors, is there a chance for PTCs and NTCs? And <diode> would benefit IMHO from a variant="[zener, schottky, photo]" plus associated parameters for them.

We think that intuitive element names should be added to the tscircuit spec, even if they're redundant/there are multiple ways to do something. Right now you would probably use a <chip /> (very general purpose), but <connector /> is a great proposal for an element.

Yes diodes should have variants, I was surprised this wasn't already in the spec and created an issue to add it: https://github.com/tscircuit/props/issues/211

Yes we would support PTCs and NTCs for resistors, in general anything that helps with simulation, part selection, design intent, functionality, placement or appearance is in scope.

		> We think that intuitive element names should be added to the tscircuit spec, even if they're redundant/there are multiple ways to do something. Definitely makes sense, the question IMHO is what is the best way to interface with existing parts libraries. Making up individual names for each of the probably hundreds of thousands of connector types is going to be a looot of work. And then, to add insult to injury, for some connectors there are so many different sub-variants as well. RJ45 with and without magnetics (I see inductors and (auto)transformers aren't present at the moment either) and LEDs, USB-C with some connectors being flush with the PCB and others that are designed to be placed in a PCB cutout... or PCIe connectors which can be had in physically closed and cutout variants (aka, an x1 socket that accepts x4/8/16 cards). I hate connectors, in case it isn't apparent :'D > Yes diodes should have variants, I was surprised this wasn't already in the spec and created an issue to add it Thanks!
