add old IPs to design

Dear @florentw

 

I want to add two AXI IPIF one master and one stream. where are those IPs in Vivado?

 

Someone wrote this for me:

you generated the AXI Interfaces with the help of vivado, but you should take the AXI IPIF

 

where should I get this IP when it is hidden? I read below post but  still no clue.

https://forums.xilinx.com/t5/Design-Entry/Instantiating-AXI-Lite-IPIF-or-other-hidden-IP-cores/td-p/326097

 

also it is old IP and why should I not use the wizard to create new Interface with Vivado?

Re: add old IPs to design

Hi @pixel2017,

 

From the PG155:

ipif.PNG

You cannot use this IP directly. Helper core are usually included in example application for IPs. Not sure which one uses the IPIF.

 

And I am not sure what is your need for the IPIF? How did you find this IP?

 

You might want to see AR#62549.

 

Why should I not use the wizard to create new Interface with Vivado?

Well you might want to ask this "Someone" for his reasons. It looks like he is still stuck in ISE and refractory to newest tools ;-)

 

The wizard is really good to create new interfaces. They are compliant with the AXI spec.

 

Regards,

 

Florent

Re: add old IPs to design

Hi @pixel2017,

 

I won't explain you how to use the IPIF as this is not supported (this is not in the IP catalog).

 

The best solution is to use the wizard for a new AXI interface. If you want to use the IPIF you are on your own and I do not recommend you to use it.

 

Regards,

 

Florent
