Memory Interface is a free software tool used to generate memory controllers and interfaces for Xilinx® FPGAs. Memory Interface generates unencrypted Verilog or VHDL design files, UCF constraints, simulation files and implementation script files to simplify the design process. Memory Interfaces supported are: DDR3 SDRAM, DDR2 SDRAM, QDRII SRAM, and DDRII SRAM, LP DDR, QDRII+ SRAM, and RLDRAM II.
