How to connect SDRAM module with Avalon-MM master

I generate a memory controller for SDR-SDRAM through SOPC-BUILDER, but I have error: "sdram.s1 must be connected an Avalon-MM master". :cool: How can I make this connection?

thanks

    Connect it with CPUs Data and/or Instruction master, if you dont know how, probably you need to study SOPC builder user guide, its very simple!

    You add the Avalon-MM master just like you added the SDRAM. The Avalon-MM master is in "Bridges and Adapters" in "Memory Mapped" as "Avalon_mm Tristate Bridge"
