Cyclone V SoC AHB BUS

In Qsys there are some Interconnect components. I use the golden system reference design. Maybe I can use this components to convert AXI to avalon ST(AXI Master Network interface) and from avalon st to AHB (AHB Slave agent).

In Qsys:

HPS(AXI MASTER)-->AXI MASTER NETWORK INTERFACE-->AHB SLAVE AGENT-->AHB SLAVE

The axi network interface converts AXI to qsys packets(avalon st) and has in qsys following signals

(write_cp, write_rp, read_cp, read_rp, altera_axi_slave)

ahb slave agent :

(altera_ahb_master, rp, cp

Can I use this two components to convert AXI to AHB?

There are any informations from altera about connecting different bus types?

How are the convertion beetween AXI and APB is done? (e.g. AXI Master and i want to connect an APB slave)

Any available 3rd party ip cores to convert an AXI to AHB?

thanks a lot
