AXI_to_AXI cascading for Kintex7

Jump to solution

Hi!

I need to cascade two AXI_Interconnects in Kintex 7 because I have more than 16 slaves in my design. I saw AXI_to_AXI connector in Xilinx documentation but this does not support Kintex FPGA. Can someone elaboarte how to do that using Kintex 7? If there is an example, then it will be even more helpful.

Thanks,

Danial

Why people don't try before asking?

Hi dinatale.ds@gmail.com 

Could you clarify where in the documentation you saw the AXI_to_AXI connector?

I am quite sure you can cascade 2 AXI interconnects on Kintex-7.

Maybe because they want me to reach 2000 accepted solutions ;) (I am still surprised no one from the community answer this before as, as you said, this is an easy one as you could just try).

But if everybody was reading fully reading the doc, googling before asking, trying quickly or spend 10/15min debugging, the activity of the forums will probably dropping by 50%.

Hi dinatale.ds@gmail.com 

Looking a the DS803 I see where your confusion is coming from.

My advise is to use the latest version of vivado and a block design to add IPs. It should have all the checks to tell you if the connection you want to do is possible or not.

Hi,

Thanks for your kind response. But I am working in non-project mode with Vivado 14.4
Is it possible for you to share a VHDL example of the cascading?

Hi,

I understand this cascading theoratically but since I am a newbie so I am stuck with the implementation. Can you please share a VHDL example of the same? I am restricted to work in non-project mode only with Vivado 14.4
