Converting DE2 Design to a CIII Board?

I am trying to convert a project designed for a DE2 board to a CIII DSP Board (EP3C120) 

 

This entails modifying the design to use DDR2 memory instead of SDRAM. Before I give myself a crash course on SD and DDR2 memory addressing/logic, does anyone have any hints to make my job easier? 

 

To be specific, the original design is for a DE2-70 board and has SSRam defined in the SOPC builder. Further, it has its own "SD-RAM Control 4 Port" verilog files for the control interface/data path. 

 

Thanks.

You should change pins very correctly from cyclone II(DE) to cyclone III .USE pin maps of both cyclone devices (voltage and names).Create new pins map and load it into your Quartus project. It's routine but very important because altera's tutorial warned that pins connected in wrong way can burn circuit.
