The SC_System has been deployed on a Nexys4DDR FPGA board, modules involved are located into boards/nexys4ddr and src/deploy/ folders. The design interconnects the board DDR memory and the UART to respectively the Memory and Item interfaces. The figure below shows a schematic block of the top module:
