I have asserted RxmIrq and app_msi_req signals (Signals that are responsible for Interrupts as it's said in the IP compiler user Guide) every 100 cylces.

In simulation, I saw that it is asserted app_int_ack every time that RxmIrq and app_msi_req are asserted. BUT NOT app_msi_ack is turn to 1.

I guess that this is happend because of the configuration of the testbence ( INTx is enabled instead of MSI).

Nevertheless I can not see interrupts from the side of the software.

Any advices ?

Do I miss something important?

How can I set the simulation from INT to msi mode?

Thanks you.
