You can just print each flit (cout << *t_flit) in InputUnit.cc wakeup function
..

I found this function that can print out the flit data during the simulation.
But I don't know how to call it during the simulation.
// Flit can be printed out for debugging purposes
void
flit::print(std::ostream& out) const
{
out << "[flit:: ";
out << "PacketId=" << m_packet_id << " ";
out << "Id=" << m_id << " ";
out << "Type=" << m_type << " ";
out << "Size=" << m_size << " ";
out << "Vnet=" << m_vnet << " ";
out << "VC=" << m_vc << " ";
out << "Src NI=" << m_route.src_ni << " ";
out << "Src Router=" << m_route.src_router << " ";
out << "Dest NI=" << m_route.dest_ni << " ";
out << "Dest Router=" << m_route.dest_router << " ";
out << "Set Time=" << m_time << " ";
out << "Width=" << m_width<< " ";
out << "]";
}

Yes, I understand that. DPRINTF and std::cout work fine with me too.
But i'm sorry, my question wasn't about using DPRINTF, I already used it before
and it worked fine. My question is about the flit inside the Mesh_XY routing, i
want to debug and print the flits or packets to trace it during the simulation.
function int RoutingUnit::outportComputeXY(RouteInfo route, int inport,
PortDirection inport_dirn)
inside mem/ruby/network/garnet/RoutingUnit.cc, doesn't mention anything about
the flits or packets. The route variable has the source and destination
information and the network interface, i want to get the flit or the packet ID
during the simulation - I tried to import #include
"mem/ruby/network/garnet/flit.hh"
But I still can't see the flit ID or Packet ID. I just want to trace each
packet or flit during the simulation.

Did you run at .debug mode while using Dprintf?
Also, I think std::cout will also work for printing.
