DSP Builder procedure to get data from A/D board using SPI

In this moment i dont know what Should I do. I was thinking that the Avalon Master MM of DPbuilder could be connected to Avalon Slave MM of SPI Core.

I suppose that the signals needed in the SPI slave I have to generate them by myself.

Then the procedure could be. first, generate the verilog code for SPI slave. Second find the way to get data from verilog code to simulink. Someone could help me.

Thank you for your help.:)
