Yes that's the right name. Sorry about that.

Ensure that your components are only connected behind the pipeline/clock crossing bridges. If as an example you have:

CUP Data master > pb_cpu_to_flash > flash, then you shouldn't have any direct connection between the CPU Data master and the flash. They should only be connected through the bridges.

The assign base address should really solve your problem, it just needs to move the ddr or the flash to prevent overlapping...
