DSP Builder and SOPC Builder

Hello

I am working with EP2S60 stratix II Development Kit.

I want to link my design in MATLAB to other SOPC components.

I make a simple design in MATLAB with DSP Builder and i add Avalon Port to my design. Then with SOPC Builder in Quartus II i make a core with cpu and on chip memory and UART and JTAG UART and my design. Quartus produce 2 components. 1 related to my design and 1 related to SOPC component (cpu and UART and ...). But in Quartus i can just assign pin just to my MATLAB design not to

SOPC components. It looks SOPC components are unknown for Quartus. also i can program my board just by my own design not SOPC components.

If any one has any comments about this proplem (MATLAB design and SOPC link) plz sent
