Thank you for the answer, but I think that you mean different kind of export

I don't want to export actual wires and use it out of Qsys, I want to export from Qsys where are these wires connected.

Eg. If I have component A and irq lane 0 and have irq 2, 3, 4 connected there I need to output some file which will have something like this:

irq0,2 -> A,irq0

irq0,3 -> A,irq1

irq0,4 -> A,irq2

I need to automatize this export so that when I change system in Qsys I will get file which I will parse to C header, DTS or whatever to get mapping into driver so that driver will know exectly where to expect interrupts from which device...
