Abse - @Seve what should we do about vias in cr...

imo we should detect traces connected to crystals and warn if it has vias

<@757706909351411845> wdyt?

<@398467566588264449> maybe you'd be interested in implementing impedence matching

i think we already do this

but there are just a ton of things that can go wrong

so it needs refinement

e.g. the crystals, if they aren't using crystal elements, need to have a warning to tell the user to use crystal elements

we should honestly like block autorouting if the crystal paths aren't planned

the crystal path is really bad on this one too

otherwise this board is like pretty sweet

even the usb is somehow impedance matched(!)
