Avalon MM slave and interrupt

Hi folks,

I have written an Avalon Slave peripheral to interface to an FTDI chip. I this peripheral I have inlcuded an IRQ signal that is driven from the FTDI chip. However when I add this peripheral to Qysys and make all the necessary connections (including setting an IRQ number) I get some warnings and errors on generation. Namely that the irq sender is not connected to a receiver, but yet in the messages box at the bottom of Qsys it says 0 errors, 0 warnings.

I have included the warnings and errors I get on generation above.

Can anybody give me an idea of where I am going wrong?

Many thanks

    Could you include your hw.tcl for your Avalon Slave? I want to take a quick look if you don't mind.

    For starters, is the add fileset file and path correct?:

    add_fileset QUARTUS_SYNTH QUARTUS_SYNTH "" ""

    set_fileset_property QUARTUS_SYNTH TOP_LEVEL FT245_Avalon_Interface_RW

    set_fileset_property QUARTUS_SYNTH ENABLE_RELATIVE_INCLUDE_PATHS false

    add_fileset_file "FT245_avalon_interface RW.vhd" VHDL PATH "../Avalon/FT245_avalon_interface RW.vhd" TOP_LEVEL_FILE

    Probably you may want to rename for consistency.
