AXI Interconnect

How peripheral_aresetn and interconnect_aresetn are different? where do we use them specifically ? What happens if we interchange them while connecting?

I guess it's because people wanted to be sure that the interconnect is ready before peropherals attempt to make transactions. But if all axi peripherals are properly coded, they should delay transactions until both sides of the axi4 link are out of the reset phase because axi4 is a 2 way handshaking mechanism where both parties must agree to the transaction.
