I'm having a big problem with AXI Stream in SysGen Tool ( and also in Model Composer).
I've already read the tutorials and previous message in this forum, but I don't understand the workflow.
Is there anyone that can tell me simply HOW to configure an AXI Stream ?
I understand I have to put three signals named using the same prefix, but when I export this in Vivado, It doesn't work and port is not an AXI Stream.
Thank you so much

In the Gateway In, please ensure you set interface type to AXI4-Stream, the interface type isn't AXI4-Stream in the screenshot, but it shows you where to set the correct type.I can't remember since which version sysgen starts to support AXI- Stream. If you don't see this option, please upgrade your Sysgen version to the latest v2018.1
In the meantime, please take a look at AXI4-Stream Support in System Generator section (page 98 and onwards)

I'm sorry but there's no AXI-STREAM Option in System Generator 2018.1 .... so the problem is unresolved.

@enprevo "I'm sorry but there's no AXI-STREAM Option in System Generator 2018.1 .... so the problem is unresolved."
If you are using the SysGen "IP Catalog" export flow, AXI streams will be automatically inferred from gateway names of the form:
See page 98 of UG948 2018.1 .
p.s. I've done this successfully using the "IP Catalog" flow in 2016.x and 2017.x, but haven't personally checked that it is still working in 2018.1.
EDIT: Make sure the "Auto Infer Interface" checkbox is selected under System Generator Icon=>Compilation(IP Catalog)=>Settings.
