Modify SDRAM Controller Cyclone ii - DE1

Hi, 

I generated a SDRAM Controller using the guide "Using the SDRAM on Altera’s 

DE1 Board with VHDL Designs". This guide illustrate how to create a SDRAM Controller using SOPC builder in Quartus II. 

 

It working properly but I need to generate from myself addresses where controller must write/read... 

 

So, how can I modify the controller?I'd like modify se controller using SOPC because i easier than using code... 

 

Any suggestion? 

Thank you
