Hi, I ran into the same situation that you have. As there is no solution, just workaround, even from Cadence support. Well, there are many properties you can attach to via, but this exception is one of them. I asked for product improvement, it is NOT going to be considered. So, I resorted to use manual voids.

Inside this board (but not shown) is a separate 3.3V plane. What I would like to do is have the (3) vias at the top of the picture (coming off the electrolytic cap) make connection with the internal 3.3V plane and then connect to the electrolytic cap with traces as shown in the picture. The 3.3V then travels down this small external plane coming into contact with some other capacitors and ultimately ends at the two vias at the bottom which carry the current from the top side of the board to the bottom side of the board where in turn there are two traces that connect to two bottom side pads of a bottom side connector. Now for my problem ? the two vias at the bottom of the light blue area are now also connected to the INTERNAL 3.3V master plane (for clarity sake I did not turn that plane on). I DO NOT WANT them to connect to the internal 3.3V plane. I want to force the 3.3V signal to have to travel through the caps and then into the connector pads on the external layer only. Is there a setting or a property that I can add to those two vias so that they get connected to the small external 3.3V copper plane, but NOT to the INTERNAL 3.3V master plane? Any help, especially on a weekend, would be greatly appreciated. Thanks in advance and I hope all who are listening will have a great weekend ? at least what is remaining of it. Thanks again.
