Qsys custom components irq hookup

How do I get the irq to hook up right using Qsys? I am using 12.1SP1. I am working off of an example project that has several peripherals already connected and working. The architecture is such that the main system has the CPU and it instantiates several sub systems, one of which has most of the peripherals. This is where I am working from.  

 

I have the interface defined as a irq interface and assigned it to my avalon bus. When I right click on the instantiation and go to connection instance.interrupt_sender(no connectables). If I look at this same spot in one of the ones that was already there it says jtag_uart.irq (exported) .  

 

How do I get mine to go to exported?  

 

Thank you.

What you need to do is right-click on the instance, and on the popup menu select Filter->All Interfaces By default, the IRQ's are hidden in the GUI presentation. 

 

After doing that, your instance 'irq' element will be displayed. Export it like you would export any other interface, and connect it in your top level.
