AXI interface in Qsys 11.1

Hello.

I have a question regarding the use of AXI interconnect in Qsys 11.1.

I have the VHDL component, which must communicate with NIOS processor through AXI interface.

First of all, I don't see that NIOS processor has AXI interface at all.

Yet, I see that 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.

Question:

1) Does it mean that for connecting my IP to NIOS I 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 which must be set somehow. Can anyone explain what do they mean?

Thanks in advance.

Best regards,

Dima.
