Hi,

I know it is possible to have multiple avalon buses in one FPGA, but how can I do it?

somebody know where I can found a tutorial?

Thanks,

    If you have two different Avalon masters (eg two different nios cpu) they can do bus cycles to different Avalon slaves at the same time.

    Arbitration only happens when two masters try to access the same slave at the same time.
