Multiple Avalon Masters and

About the interrupt thing, you are limited to one interrupt sender/receiver per slave/master port. So if you create a component with two slave ports you can have one interrupt per port. You would want to make sure that those interrupts don't fire at the same time if a master is connected to both ports since you'll end up with two interrupts for a single event which would get a bit confusing to handle in software :)

Users who want to have multiple interrupts from the same slave port should have a register that can be read back to determine which event occurred as apposed to attempting to use multiple interrupt lines (which isn't supported anyway)
