if one neighbor in one case is connected to a different net then it shouldn't produce a lot more masters. as far as i can tell they don't extract with any context outside the tile. by the way they consturcted it you'll never see coupling outside the tiles.but if you're coupling from one net to another net inside a tile you could theoretically hook up two different nets within that tile.
here lemme do a whiteboard cause i think we need a picture. oh, i was gonna look at communnicator but yeah this is fine. except everything is grayed out for me, you like have to let me do stuff. so like, okay. yeah. don't worry, i draw badly too, so you're not gonna miss much. so this is a and b, and at the top level they're connected to a representative net, this is a prime, right. and you have another instance here, and this is still a prime. it could be going some completely different way, but you're still coupled to it. does that make sense?
i don't know if that actually happens, that's just the case i'm trying ot describe.
well is it always the case that a and b come from the same tile?? i don't know if it occurs or not but you could construct a case where.. let me do the same thing over here
but, when you stitch the thing together, right, it all becomes one net. b double prime, or something. are we saying that a couples to b, or are we saying that a prime couples to b prime versus a couples to b double prime?? you could wind up having to uniquify these two a primes because b versus b prime is different.
