Where is 16-bit shared interrupt port IRQ_F2P[15:0]?

I have a question about General Interrupt Controller ZYNQ.

 

In Vivado i added

- ZYNQ7 Processing System
- 2 AXI Timer
- AXI Interconnect

I need to have two interrupt request and handle two interrupt from PL.

 

In ZYNQ i enabled

- PL-PS interrupt port IRQ_F2P

I can connect interrupt request output axi_timer_1 to IRQ_F2P[0:0].

How can i connect interrupt request output axi_timer_1?

Where is IRQ_F2P[1]?

 

Where is 16-bit shared interrupt port IRQ_F2P[15:0]?

 

Thank you (from Moscow).

Hello,

Good question. What you need to do is use a concatenate block to combine all your interrupt lines into one 'bus' which can then be connected to the IRQ_F2P pin on the PS7 block. It will automatically update the width of that port for you.
