Wiring Blocks Together in Encounter...help!

I have a design where I have a relatively small amount of digital, which is contained in a corner of the chip. The rest is macrocells. I am trying to get Cadence to sroute the power on each of those macrocells to the power pad, but I can't get it to work. As it stands now, the standard cell rows are limited to the area where I want digital. The digital area has it's own ring, with stripes that only go through the digital section of the chip. The rest of the chip is just blank (except for macrocells, such as charge pumps, that are randomly placed within the core). If I stick a block ring around the macrocell, the sroute only routes the power from the power pad to the closes block ring, and leaves the rest of the block rings disconnected! I want it to wire ALL of my block rings up to the power pad. Help! How are block rings supposed to be used? It does successfully wire the block pins to the block rings, but it just doesn't want to wire the block rings to anything. I have no rows, stripes, etc, in the body of my chip - only inside the ring that holds the digital. Any help would be appreciated. Thanks! Ben
