@User, @User: You can stack the two types of mim cap, too, but then note that the top plate of the bottom capacitor is always connected to the bottom plate of the top capacitor. I have not seen an explicit rule for it in SkyWater, but the general rule is never to connect downward from a bottom plate, but to always connect upward (like antenna rules, this has to do with accumulating charge on the capacitor during manufacture). That's why the connection up from the bottom plate is provided on the side. That's the best place to connect to. The top plate, you can just connect to directly.
