    The procedure I described must be made from SOPC builder, not the IDE. After that you must regenerate the SOPC system. Then go to the system library properties in the IDE and the RAM should be there.

    Open the component editor on your custom component, go to the Interfaces tab, and in your Avalon slave interface, open the "Deprecated" section and check the "Memory device" option.

    Contrary to what the name suggests this option isn't deprecated at all and is required to use the device as memory in the IDE.
