Sending interrupt to a custom logic.

Hi, 

I hope I'm posting in the right section. 

I need a DMA Controller for my project. I am not using a NIOS system with it and I want to trigger a custom logic circuit when the data transfer is over. From the manual of DMA controller in SOPC builder, I got the idea that I can read the Status register of the Controller repeatedly to check whether the transfer is finished or not. Which i might do, but I was wondering if it is possible to use the interrupt that the controller generates at the end of a transaction to trigger the circuit. Is it possible to receive the interrupt with a my circuit? If possible, how? I don't see any way to export or use any bridge with the 'irq' terminal present in the DMA CONTROLLER in SOPC builder. 

 

Thank you.

If the DMA module has IRQ sender, then create Your own component, which has IRQ receiver signal.
