Dear Andreas, Thank you for your hint,
I noticed that inside the Packet class, the field "dest" is only an integer, so packet can not keep a history of its whole routing path, and therefore multi-hop routing is not possible in current version of gem5. (Is this correct?) Do you think if I add a data-structure such as stack to the Packet class, I would be able to route back the response over multiple hops? It might be a starting point for supporting connection of multiple interconnects in gem5.
