Xilinx DDR2 controller with Wishbone interface
 
This is a Xilinx technology-dependent DDR2 memory controller, based on a
controller from Xilinx's memory interface generator (MIG), with a small cache
memory and Wishbone wrapper.
 
The xilinx_ddr2_wb_if.v is a 3-master arbiter for the controller.
The xilinx_ddr2_if.v is the actual interface between the Wishbone bus and
Xilinx MIG control interface.
 
When synthesizing, take note of the xilinx_ddr2_if_cache module, that is a
dual-port memory, with different aspects on each size, and cannot be inferred.
The NGC should be in the appropriate place in the synthesis or backend
directories.
 
Wishbone B3-compliant bursting is yet to be implemented.
