Qsys

Hi.

Did anyone try to use AXI interface in Qsys 11.1? It's supposed to be supported there.

I was expecting to see AXI interface on NIOS processor, but Only Avalon interfaces exist. How can an IP with AXI slave interface be connected to NIOS?

Should the protocol conversion from Avalon to AXI be performed by means of some Altera IPs?

In addition, In Components library of Qsys under Qsys Interconnect there's "AXI Interface" section with 2 components : AXI Master Network Interface and AXI Slave Network Interface.

AXI Slave Network Interface accepts command packets on avalon_streaming interface and issues the resulting transactions to the AXI interface.

1) Does it mean that for connecting AXI IP to NIOS we should first translate Avalon-MM interface of NIOS to Avalon-ST interface, and after that use AXI Slave Network Interface?

2) There's no any documentation on AXI Master and Slave blocks. There're a lot of parameters inside and it's unclear how to set them. Does anyone have a clue how to deal with it?
