One way is to delete the SIGNAL_MODEL property of R1; that will give you two nets instead
of one xnet.

Hi all,

I ran into this a while ago, and then forgot about it. I have an xnet, let's say NET1 from U1 to R1.1, then NET2 from R1.2 to U2. On NET1 I'd like to control something, in this case number of vias to be no more than 2, but it could be other things too. The resistor isn't right next to the IC, so the router will make the connection, and thus has the potential of adding more vias than I can allow. I don't care how many vias are on the NET2 portion of the xnet. If I put a rule on NET1, it applies that rule to the xnet, making it impossible to route the entire connection because it needs more than 2 vias to route NET2. Is there a way to make properties apply at the net level rather than the xnet level?
Thanks,


Jean
