    Add the following to your IP TCL file generated by SOPC (after you created component in SOPC)

    --- Quote Start ---

    set_interface_property <interface_name> isMemoryDevice true

    --- Quote End ---

    <interface_name> is the name that defined by SOPC

    Did you define your custom component as a memory component? If not, SOPC Builder will not see your SSRAM as a viable component for the reset and exception vectors.

    Best regards,
