As a port on the receiving side, it is exclusive because it is an internal connection in Platform Designer or exported to the outside.

There is one of the following implementation methods.

Export the interrupt-raising signal once and connect it outside of Platform Designer
Qsys provides an IP called IRQ_Bridge, so use it to connect interrupts from user modules outside of Platform Designer.

As a basic concept, Platform Designer is an internal connection, so we recommend using the IRQ Bridge.
