TDA3MV: Dual memory controller PCB tracing (with ECC)

Part Number:TDA3MV

Hello,
we making designs of some ADAS devices on TDA2, TDA3. Sure we have NDA.
We want use dual memory controller configuration. But all that we seen before (EVM and other designs) using only one memory controller.
Where can we get PCB tracing (design or recommendations) for dual controller + ECC?
Recommendation about tracing of FCBGA 784 (ABZ package) will be useful too.
