dual-MCB x32 interface design

As stated during X-Fest, Xilinx is working on an Application Note that will give designers a x32 memory interface using two MCBs and two x16 memory components.  This logic is built from fabric and makes the interface appear internally at the User Logic to be a x32 interface.  However, externally, the physical connections between memory chips and FPGA are completely independent.  Each memory must independently be connected to the required I/O pins for each MCB.  Address and control signals are NOT shared between the two chips.

 

I'll post again when this design is available.
