For Cyclone , hoe do I employ CB_P2A_AVALON_ADDR_B0 to get the BAR size == IP span

Team, I have seen documentation describing CB_P2A_AVALON_ADDR_B0 as an offset I believe do the BAR size will reflect the actual span and not the number of bits to reach the Avalon MM address...

The attachment depicts the PCIe -> Avalon MM translation ... I see the offset values as input to the PCIe RTL but when I set them to non-zero values , a checker flags an error during synthesis ..

How do I take advantage of the offset values to make the BAR the same size as the slave IP the BAR master is connected to ?

Thanks, Bob.
